LC87F2C64A
CMOS IC
64K-byte FROM and 2048-byte RAM integrated
8-bit 1-chip Microcontroller
Overview
The SANYO LC87F2C64A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time
of 83.3ns, integrates on a single chip a number of hardware features such as 64K-byte flash ROM (onboard
programmable), 2048-byte RAM, an on-chip debugger, sophisticated 16-bit timer/counter (may be divided into 8-bit
timers), a 16-bit timer/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), four 8-bit timers with a
prescaler, a calendar function (RTC), High-speed clock counter, a synchronous SIO interface (with automatic block
transmission/reception capabilities), an asynchronous/synchronous SIO interface, two channels of UART interface (full
duplex), four 12bit-PWMs, a 12/8-bit 16-channel AD converter, a system clock frequency divider, an internal reset
function and a 28-source 10-vector interrupt feature.

„Timers
Timer 0: 16-bit timer/counter with a capture register
Mode 0: 8-bit timer with an 8-bit programmable prescaler (with an 8-bit capture register) × 2 channels
Mode 1: 8-bit timer with an 8-bit programmable prescaler (with an 8-bit capture register) + 8-bit counter
(with a 8-bit capture register)
Mode 2: 16-bit timer with an 8-bit programmable prescaler (with a 16-bit capture register)
Mode 3: 16-bit counter (with a 16-bit capture register)
Timer 1: 16-bit timer/counter that supports PWM/toggle outputs
Mode 0: 8-bit timer with an 8-bit prescaler (with toggle outputs) + 8-bit timer/counter with an 8-bit prescaler
(with toggle outputs)
Mode 1: 8-bit PWM with an 8-bit prescaler × 2 channels
Mode 2: 16-bit timer/counter with an 8-bit prescaler (with toggle outputs) (toggle outputs also possible from
the lower-order 8 bits)
Mode 3: 16-bit timer with an 8-bit prescaler (with toggle outputs) (The lower-order 8 bits can be used as
PWM.)
Timer 4: 8-bit timer with a 6-bit prescaler
Timer 5: 8-bit timer with a 6-bit prescaler
