DESCRIPTION
The
PD753304 is one of the 75XL series 4-bit single-chip microcontroller chips and has a data processing
capability comparable to that of an 8-bit microcontroller.
Since it inherits the 75X series CPU, it has upward compatibility.
While the conventional 75X series products with an on-chip LCD controller/driver use an 80-pin package, the
PD753304 is sold as a pellet/wafer to make it possible to be built into portable devices with an LCD display
function, etc.
For detailed function descriptions, refer to the following user's manual.
PD753304 User's Manual: U12020E
FEATURES
RC oscillation circuit on chip
Main system clock: f
CC
= 3.6 MHz (typical value with 6.8-k
external resistor connected. An internal
10-pF (typ.) capacitor is provided.)
Subsystem clock : f
CT
= 47 kHz (typ.) (Both a resistor and a capacitor are provided internally.)
Processing can be started immediately after standby mode is released.
Oscillation of the subsystem clock can be stopped in STOP mode.
Supply voltage: V
DD
= 2.5 to 5.5 V
On-chip memory
Program memory (ROM) : 4096
8 bits
Data memory (RAM)
: 256
4 bits
Variable instruction execution time function useful for power saving

Caution The
PD753304 is sold as a pellet/wafer. However, an ES product in 42-pin ceramic shrink DIP
is also available.
Remark XXX is a ROM code suffix.
For the pellet/wafer, consult NEC because an agreement concerning quality must be made.
