General
Description
The EPROM-based EP220 and EP224 devices feature a flexible I/O
architecture and implement 150 usable (300 available) gates of custom
user logic functions. EP220 and EP224 devices can be used as upgrades for
high-speed bipolar programmable logic devices (PLDs) or for 74-series LS
and CMOS (SSI and MSI) logic devices in high-performance
microcomputer systems.

EP220 & EP224 Classic EPLDs
Compared to bipolar devices of equivalent speed, the EP220 and
EP224 offer lower power consumption, faster input-to-non-
registered-output delay (
t
PD
) in combinatorial mode, and higher
counter frequencies in registered applications. This added
performance supports faster state machine designs compared to
bipolar devices, and provides additional timing margin for existing
designs. The EP220 and EP224 are ideal for high-volume
manufacturing of high-performance systems. These devices improve
performance and decrease system noise, power consumption, and
heat generation.
Functional
Description
Figure 1
shows block diagrams of the EP220 and EP224 device
architectures. The EP220 has 10 dedicated inputs and 8 I/O pins; the
EP224 has 14 dedicated inputs and 8 I/O pins.

Numbers in parentheses refer to the pin-out number.
The EP220 and EP224 architecture is based on a sum-of-products,
programmable-
AND
/fixed-
OR
structure. Each macrocell can be
individually programmed for combinatorial or registered output. An
inversion option allows each output to be configured for active-high or
active-low operation. Each I/O pin can be programmed to function as an
input, output, or bidirectional pin.
The EP220 and EP224 device architecture offers the following features:

Macrocells
Each macrocell includes a product-term block with 8
AND
product terms
feeding an
OR
gate. One product term is dedicated to the Output Enable
(
OE
) control of the tri-state buffer. The global logic array allows each
product term to connect to the true or complement of each input--36
inputs for the EP220, 44 inputs for the EP224--and I/O feedback signal.
See
Figure 2
.
Figure 2. EP220 & EP224 Macrocell
Macrocells can be individually configured for registered or combinatorial
operation, providing a mixed-mode operation not available in fixed-
architecture PAL devices. When registered output is selected, feedback
from the register to the logic array bypasses the output buffer. When
combinatorial output is selected, feedback comes from the I/O pin
through the output buffer, and can be used for bidirectional I/O. Unlike
PAL and GAL devices, all eight outputs on the EP220 and EP224 allow a
combinatorial feedback signal from the I/O pin to feed the logic array.
Data is clocked into the macrocell's D register on the rising edge of the
global Clock.

EP220 & EP224 Classic EPLDs
The
XOR
gate can implement active-high or active-low logic, and can use
DeMorgan's inversion to reduce the number of product terms needed to
implement a function.
If the EP220 and EP224 register outputs do not require an
OE
signal, the
internal product term can hold the output in an enabled state; if a global
OE
signal is required, any input can be dedicated to the task, and all eight
product terms can be programmed accordingly.
High-Frequency, Low-Skew Global Clock
EP220 and EP224 devices have extremely low output-pin skew: registered
output skew (
t
OCR
) is typically less than 300 ps; combinatorial output
skew
(
t
OSC
) is typically less than 400 ps. This low output-skew rate makes
EP220 and EP224 devices ideal for high-frequency system Clock
applications, including Intel Pentium microprocessors, 486-based PCs,
and PCI bus designs.
PLD
Compatibility
The EP220 and EP224 devices are a logical superset of most high-speed,
24-pin PAL/GAL devices. Industry-standard JEDEC Files from
compatible devices can be programmed into EP220 or EP224 devices.
Table 1
summarizes some of the devices that can be replaced or upgraded

Power-On
Characteristics
The EP220 and EP224 inputs and outputs respond a maximum of 1
s
after V
CC
power-up (V
CC
= 4.75 V), or after a power-loss/power-up
sequence. All macrocells that are programmed as registers are set to a
logic low on power-up.
Design Security
EP220 and EP224 devices contain a programmable Security Bit that
controls access to the data programmed into the device. When this bit is
turned on, a proprietary design implemented in the device cannot be
copied or retrieved. This feature provides a high level of design security,
because programmed data within EPROM cells is invisible. The Security
Bit that controls this function, as well as all other program data, is reset
when a device is erased.
Turbo Bit
The -10A and -12 speed grades of the EP220 and EP224 devices contain a
programmable Turbo Bit to control the automatic power-down feature
that enables the low-standby-power mode (I
CC
). When the Turbo Bit is
turned on, the low-standby-power mode is disabled. All AC values are
tested with the Turbo Bit turned on. When the device is operating with the
Turbo Bit turned off (non-turbo mode), a non-turbo adder must be added
to the appropriate AC parameter to determine worst-case timing. The
non-turbo adder is specified in the
"AC Operating Conditions"
tables in
this data sheet.
Generic Testing
EP220 and EP224 devices are fully functionally tested and guaranteed.
Complete testing of each programmable EPROM configuration element
and all internal logic elements ensures 100
%
programming yield.

shows AC test conditions.

Test programs are used and then erased during the early stages of the
device production flow. EPROM-based devices in one-time-

circuitry to allow verification of function and AC specifications during the
production flow.
Software &
Programming
Support
The EP220 is supported by the Altera MAX+PLUS II development
software, Altera programming hardware, and third-party hardware. Both
the EP220 and EP224 are supported by the Altera PLDshell Plus design
software, third-party logic compilers (e.g., ABEL, CUPL, PLDesigner,
LOG/IC, and iPLS II), and third-party programming hardware (e.g., Data
I/O).

Power-supply transients can affect AC
measurements. Simultaneous transitions of
multiple outputs should be avoided for
accurate measurement. Threshold tests
must not be performed under AC
conditions. Large-amplitude, fast ground-
current transients normally occur as the
device outputs discharge the load
capacitances. When these transients flow
through the parasitic inductance between
the device ground pin and the test-system
ground, significant reductions in observable
noise immunity can result. Numbers in
parentheses are for the EP224 device.
