DESCRIPTION
The μPD17240, 17241, 17242, 17243, 17244, 17245, 17246 (hereafter called the μPD17246 Subseries) are 4-bit single-chip microcontrollers for small general-purpose infrared remote control transmitters.
This subseries employs 17K general-purpose register system architecture for the CPU, and can directly execute operations between data memories instead of the conventional method of executing operations through an accumulator. Moreover, all the instructions are 16-bit/1-word instructions, enabling efficient programming.
FEATURES
? Infrared remote controller carrier generator (REM output)
? 17K architecture: General-purpose register system
? Program memory (ROM), data memory (RAM)
? 8-bit timer: 1 channel
? Basic interval timer/watchdog timer: 1 channel
? Instruction execution time (can be changed in two steps)
@ fX = 4 MHz: 4 μs (high-speed mode)/8 μs (normal mode)
? External interrupt pin (INT/P1B0): 1
? I/O pins: 24
? Supply voltage: VDD = 2.0 to 3.6 V
? On-chip RAM retention detector
? Low-voltage detector (mask option)
APPLICATIONS
Preset remote controllers, toys, portable systems, etc.
