SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
DESCRIPTION
M37702M2BXXXFP, M37702S1BFP
The M37702M2AXXXFP is a single-chip microcomputers
designed with high-performance CMOS silicon gate technology.
This is housed in a 80-pin plastic molded QFP. This single-chip
microcomputer has a large 16 M bytes address space, three in-
struction queue buffers, and two data buffers for high-speed
instruction execution. The CPU is a 16-bit parallel processor that
can also be switched to perform 8-bit parallel processing. This
microcomputer is suitable for office, business, and industrial
equipment controller that require high-speed processing of large
data.
(The fastest instruction at 25 MHz frequency) .................. 160 ns
• Single power supply ..................................................... 5 V ± 10%
• Low power dissipation (at 16 MHz frequency)
......................................... 60 mW (Typ.)
• Interrupts ............................................................ 19 types 7 levels
• Multiple function 16-bit timer ................................................ 5 + 3
• UART (may also be synchronous).............................................. 2
• 8-bit A-D converter ............................................. 8-channel inputs
• 12-bit watchdog timer.
• Programmable input/output
The differences between M37702M2AXXXFP, M37702M2BXXXFP,
M37702S1AFP and M37702S1BFP are the ROM size and the ex-
ternal clock input frequency as shown below. Therefore, the
following descriptions will be for the M37702M2AXXXFP unless
otherwise noted.
