LC87F5R96B
CMOS IC
FROM 98K byte, RAM 4096 byte on-chip
8-bit 1-chip Microcontroller
Overview
The SANYO LC87F5R96B 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 98K-byte flash ROM (onboard
programmable), 4096-byte RAM, On-chip debugging function, sophisticated 16-bit timers/counters (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 base timer serving as a time-of-day clock, a high-speed clock counter, a synchronous SIO interface (with
automatic block transmission/reception capabilities), an asynchronous/synchronous SIO port, two UART ports (full
duplex), an 8-bit 11-channel AD converter, two 12-bit PWM channels, a system clock frequency divider, and a 27-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 an 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
Timer 6: 8-bit timer with a 6-bit prescaler (with toggle outputs)
Timer 7: 8-bit timer with a 6-bit prescaler (with toggle outputs)
Base timer
1) The clock is selectable from the subclock (32.768kHz crystal oscillation), system clock, and timer 0 prescaler
output.
2) Interrupts programmable in 5 different time schemes.
„High-speed Clock Counter
1) Can count clocks with a maximum clock rate of 24MHz (at a main clock of 12MHz).
2) Can generate output real-time.
„SIO
SIO0: 8-bit synchronous serial interface
1) LSB first/MSB first mode selectable
2) Built-in 8-bit baudrate generator (maximum transfer clock cycle = 4/3 tCYC)
3) Automatic continuous data transmission (1 to 256 bits, specifiable in 1 bit units, suspension and resumption of
data transmission possible in 1 byte units)
SIO1: 8-bit asynchronous/synchronous serial interface
Mode 0: Synchronous 8-bit serial I/O (2- or 3-wire configuration, 2 to 512 tCYC transfer clocks)
