µPD17P236
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR SMALL GENERAL-PURPOSE INFRARED
REMOTE CONTROLLER
The µPD17P236 is a model of the µPD17236 with a one-time PROM instead of an internal mask ROM.
Since the user can write programs to the µPD17P236, it is ideal for experimental production or small-scale
production of the µPD17230, 17231, 17232, 17233, 17234, 17235, or 17236 systems.
When reading this document, also read the documents related to the µPD17230, 17231, 17232, 17233, 17234,
17235, and 17236.
Detailed functions are described in the following user's manual. Read this manual when designing your system.
µPD172×× Series User's Manual: U12795E
FEATURES
• Pin compatible with µPD17230, 17231, 17232, 17233, 17234, 17235, and 17236 (except PROM programming
function)
• Carrier generator circuit for infrared remote controller (REM output)
• 17K architecture: General-purpose register method
• Program memory (one-time PROM): 32 Kbytes (16,384 × 16)
• Data memory (RAM): 223 × 4 bits
• Low-voltage detection circuit
• Input/output of P1A0 pin, clock selection for carrier generation
