DESCRIPTION
The LZ87010 is an 8-bit, 8051-based microcontrol ler that adds
64KB of integrated Flash memory, two UART/SIOs, I
2
C, and several
mul tifunction timers. It also incorporates an 8-channel 12-bit A/D
converter, two separate 8-bit D/A converters, and low power
modes of operation.
The 8051 Enhanced Core provides a performance boost, six times
that of a standard 8051 core operating at the same frequency and
has built-in 2-wire debug support. It is software-compatible with
8031/8051 series parts.
The LZ87010 operates from 20 MHz - 40 MHz over the industrial
temperature range of -40C to +85C.
SHARP's LZ87010 design provides low power, exceptional
performance, good fl exibility, and great value in an 8-bit processor.
