PD753304
4-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
µ
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
µ
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.

FEATURES
• RC oscillation circuit on chip
· Main system clock: f
CC
= 3.6 MHz (typical value with 6.8-kΩ 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
