DESCRIPTION
The
μ
PD754244 is a 4-bit single-chip microcontroller which incorporates the EEPROM
TM
for key-less entry
application.
It incorporates a 16
×
8-bit EEPROM, a 4-Kbyte mask ROM to store software, a 128
×
4-bit RAM to store the
processing data, a processing CPU, and a carrier generator which easily outputs waveforms for infrared remote
controller.
The details of functions are described in the following user’s manual. Be sure to read it before designing.
μ
PD754144, 754244 User’s Manual: U10676E
FEATURES
On-chip EEPROM: 16
×
8 bits (mapped to the data memory)
On-chip key return reset function for key-less entry
System clock oscillation circuit
μ
PD754144: RC oscillator (external resistor and capacitor)
μ
PD754244: Crystal/ceramic oscillator
Low-voltage operation: V
DD
= 1.8 to 6.0 V
Timer function (4 channels)
Basic interval timer/watchdog timer: 1 channel
8-bit timer counter
On-chip memory
Program memory (ROM)
4096
×
8 bits
Data memory (static RAM)
128
×
4 bits
Instruction execution time variable function suited for power saving.
μ
PD754144:
4, 8, 16, 64
μ
s (at fcc = 1.0-MHz operation)
μ
PD754244:
0.95, 1.91, 3.81, 15.3
μ
s (at fx = 4.19-MHz operation)
0.67, 1.33, 2.67, 10.7
μ
s (at fx = 6.0-MHz operation)
: 3 channels
APPLICATIONS
Automotive appliances such as key-less entry, compact data carrier, etc.
Unless contextually excluded, references in this data sheet to the
μ
PD754244 (crystal/ceramic oscillation: f
X
)
mean the
μ
PD754144.
The
μ
PD754144 and
μ
PD754244 differ in the notation of their RC oscillation: whenever f
X
(RC oscillation notation
for
μ
PD754244) is described, f
CC
should be substituted for the
μ
PD754144.
