COP87L84BC
8-Bit CMOS OTP Microcontrollers with 16k Memory,
Comparators, and CAN Interface
General Description
The COP87L84BC OTP (One Time Programmable) micro-
controllers are highly integrated COP8
TM
Feature core de-
vices with 16k OTP EPROM memory and advanced features
including a CAN 2.0B (passive) interface and two Analog
comparators. These multi-chip CMOS devices are suited for
applications requiring a full featured controller with a CAN in-
terface, and 8-bit 39 kHz PWM timer, and as pre-production
devices for a masked ROM design. Pin and software com-
patible 2k ROM versions are available (COP884BC) with a
range of COP8 software and hardware development tools.
Features include an 8-bit memory mapped architecture, 10
MHz CKI (-XE = crystal oscillator) with 1s instruction cycle,
one multi-function 16-bit timer/counter, 8-bit 39 kHz PWM
timer with 2 outputs, CAN 2.0B (passive) interface,

serial I/O, two Analog comparators,
two power saving HALT/IDLE modes, idle timer, MIWU, soft-
ware selectable I/O options, low EMI 4.5V to 5.5V operation,
and 28 pin packages.
Note: The companion devices with CAN interface, more I/O
and memory, A/D, and USART are the COP87L88EB/RB.

Note 2: Maximum rate of voltage change must be less than 0.5 V/ms
Note 3: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at V
CC
or GND, and outputs open.
Note 4: The HALT mode will stop CKI from oscillating in the Crystal configurations. Halt test conditions: All inputs tied to V
CC
; L, and G port I/Os configured as outputs
and programmed low; D outputs programmed low. Parameter refers to HALT mode entered via setting bit 7 of the G Port data register. Part will pull up CKI during
HALT in crystal clock mode.
Note 5: HALT and IDLE current specifications assume CAN block and comparators are disabled.
