LC87F2R04A

Overview

The SANYO LC87F2R04A 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 4K-byte flash ROM, 128-byte RAM, an On-

chip-debugger, sophisticated 16-bit timers/counters (may be divided into 8-bit timers), two 8-bit timers with a prescaler,

an asynchronous/synchronous SIO interface, a 12-bit/8-bit 8-channel AD converter, an internal reset and a 12-source 8-

vector interrupt feature.

Features

Flash ROM

• Capable of on-board programming with wide range (2.2 to 5.5V) of voltage source.

• Block-erasable in 128 byte units

• Writable in 2-byte units

• 4096 × 8 bits

RAM

• 128 × 9 bits

Minimum Bus Cycle

• 83.3ns (12MHz at VDD=2.7V to 5.5V)

• 100ns (10MHz at VDD=2.2V to 5.5V)

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