F2MC-8L MB89120/120A Series
MB89121/P131/123A/P133A/125A/P135A/
MB89PV130A
s DESCRIPTION
The MB89120 series is a line of single-chip microcontrollers containing a compact instruction set and a great
variety of peripheral functions such as a timer, serial interface, and external interrupt. The MB89120A series is
an extended variant of the MB89120, with a remote control transmission function and wake-up interrupt channels.
s FEATURES
• F2MC-8L family CPU core
• Low-voltage operation
• Low current consumption (allowing for dual clock)
• Minimum execution time : 0.95 µs at 4.2 MHz
• 21-bit timebase counter
• I/O ports : Max. 36 ports
• External interrupts : 3 channels
• External interrupts (wake-up function) : 8 channels (only in the MB89120A series)
• 8-bit serial I/O : 1 channel
• 8-/16-bit timer/counter : 1 channel
• Built-in remote-control transmitting frequency generator (only in the MB89120A series)
• Low-power consumption modes (stop mode, sleep mode, watch mode)
• Package : QFP-48
• CMOS technology

s PROGRAMMING TO THE EPROM ON THE MB89P131
The MB89P131 is a one-time PROM version of the MB89121.
1. Features
• 4-Kbyte PROM on chip
• Equivalency to the MBM27C256A in EPROM mode (when programmed with the EPROM programmer)
2. Memory Space
Memory space in EPROM mode is diagrammed below :

3. Programming to the EPROM
In EPROM mode the MB89P131 functions equivalent to the MBM27C256A. This allows the EPROM to be
programmed with a general-purpose EPROM programmer by using the dedicated socket adapter. Note, how-
ever, that the electronic signature mode cannot be used.
• Programming procedure
(1) Set the EPROM programmer to MBM27C256A.
(2) Load program data into the EPROM programmer at 7000H to 7FFFH (note that addresses F000H to
FFFFH while operating as a single chip correspond to 7000H to 7FFFH in EPROM mode) .
(3) Program with the EPROM programmer.
