DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD753304  
4-BIT SINGLE-CHIP MICROCONTROLLER  
DESCRIPTION  
The µPD753304 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  
µPD753304 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.  
µPD753304 User’s Manual: U12020E  
FEATURES  
RC oscillation circuit on chip  
·
Main system clock: fCC = 3.6 MHz (typical value with 6.8-kexternal resistor connected. An internal  
10-pF (typ.) capacitor is provided.)  
·
Subsystem clock : fCT = 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: VDD = 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  
·
·
1.1, 2.2, 4.4, 17.8 µs (in fCC = 3.6 MHz operation)  
85.1 µs (in fCT = 47 kHz operation)  
Programmable LCD controller/driver on chip  
Sold as a pellet/wafer to make it possible to be built into portable devices with an LCD display function  
APPLICATION  
Small LCD display device, etc.

Caution The µPD753304 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.
