HMS81C2232/48, HMS81C2332/48
CMOS Single-Chip 8-Bit Microcontroller
with VFD Controller & VFD Driver
1. OVERVIEW
1.1 Description
The HMS81C2232/48 is advanced CMOS 8-bit micro-controller with 32/48K bytes of ROM(EPROM). This is a powerful micro-controller
which provides a highly flexible and cost effective solution to many VFD applications. This provides the following standard features : 32K/
48K bytes of ROM(EPROM), 1K bytes of RAM, 8-bit timer/counter, 8-bit A/D converter, 6-bit Watch dog Timer, Programmable Buzzer
Driving Port, Serial Peripheral Interface, 8-bit remote control timer, on-chip oscillator and clock circuitry. It also comes with high voltage
I/O pins that can directly drive a VFD(Vacuum Fluorescent Display). In addition, the HMS8XC2232/48 support power saving modes to
reduce power consumption.

1.4 Development Tools
The HMS81C22xx/23xx are supported by a full-featured macro
assembler, an in-circuit emulator CHOICE-Dr.
TM
and OTP pro-
grammers. There are third different type programmers such as
emulator add-on board type, single type, gang type. For mode de-
tail, Refer to “25. OTP PROGRAMMING” on page 112. Macro
assembler operates under the MS-Windows 95, 98, NT, 2000,
XP
