MOS INTEGRATED CIRCUIT
µPD17P228
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR SMALL GENERAL-PURPOSE INFRARED
REMOTE CONTROLLER
DESCRIPTION
The µPD17P228 is a model of the µPD17228 with a one-time PROM instead of an internal mask ROM.
Since the user can write programs to the µPD17P228, it is ideal for experimental production or small-scale
production of the µPD17225, 17226, 17227 or 17228 systems.
When reading this document, also read the documents related to the µPD17225, 17226, 17227 and 17228.
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 µPD17225, 17226, 17227 and 17228 (except PROM programming function)
• Carrier generator circuit for infrared remote controller (REM output)
• 17K architecture: General-purpose register method
• Program memory (one-time PROM): 16 Kbytes (8192 × 16)
• Data memory (RAM): 223 × 4 bits
• Pull-up resistor can be connected to RESET pin
• Low-voltage detection circuit (WDOUT output)
• Supply voltage: VDD = 2.2 to 3.6 V (fx = 4 MHz: high-speed mode, 4 µs)
VDD = 3.0 to 3.6 V (fx = 8 MHz: high-speed mode, 2 µs)
APPLICATIONS
Preset remote controllers, toys, and portable systems

1. DIFFERENCES AMONG µPD17225, 17226, 17227, 17228 AND µPD17P228
µPD17P228 is equipped with PROM to which data can be written by the user instead of the internal mask ROM
(program memory) of the µPD17228.
Table 1-1 shows the differences between the µPD17225, 17226, 17227, 17228 and µPD17P228.
The differences among these five models are the program memory and mask option, and their CPU functions and
internal hardware are identical. Therefore, the µPD17P228 can be used to evaluate the program developed for the
µPD17225, 17226, 17227, and 17228 system. Note, however, that some of the electrical specifications such
as supply current and low-voltage detection voltage of the µPD17P228 are different from those of the
µPD17225, 17226, 17227, and 17228.
