LC87F2932A

Overview

The LC87F2932A 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 32K-byte flash ROM (onboard

programmable), 2048-byte RAM, an on-chip debugger, 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, day and time counter, a high-speed clock counter, a

synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous

SIO interface, a UART interface (full duplex), an 8-bit 13-channel AD converter, two 12-bit PWM channels, a

system clock frequency divider, frequency variable RC oscillation circuit, and a 26-source 10-vector interrupt feature.

Features

Flash ROM

• Capable of on-board-programming with wide range, 3.0 to 5.5V, of voltage source.

• Block-erasable in 128-byte units

• Writable in 2-byte units

• 32768 × 8 bits

RAM

• 2048 × 9 bits

Minimum Bus Cycle

• 83.3ns (12MHz)

VDD=3.0 to 5.5V

• 125ns (8MHz)

VDD=2.5 to 5.5V

• 250ns (4MHz)

VDD=2.2 to 5.5V

Note: The bus cycle time here refers to the ROM read speed.
