LC87F7932B
CMOS IC
32K-byte FROM and 2048-byte RAM integrated
8-bit 1-chip Microcontroller
Overview
The SANYO LC87F7932B is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time
of 250ns, integrates on a single chip a number of hardware features such as 32K-byte flash ROM (onboard
programmable), 2048-byte RAM, an on-chip debugger, a LCD controller/driver, 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 real time clock function (RTC), a synchronous SIO interface (with automatic block
transmission/reception capabilities), an asynchronous/synchronous SIO interface, a UART interface (full duplex), a 12-
bit/8-bit 7-channel AD converter, a high-speed clock counter, a system clock frequency divider, a power on reset
function and a 21-source 10-vector interrupt feature.
