Versa Mix 8051 MCU with LCD Controller and ADC
Overview
The VMX51C900 is an 8-bit microcontroller with 8KB of
Flash memory, 256 bytes of RAM and based on the
architecture of the standard 80C51 microcontroller.
The VMX51C900 includes extra features such as a 4
Channel 8-bit A/D Converter, 2 PWM outputs and 14
segment x 4 common LCD driver. The VMX51C900
hardware features make it a versatile and cost-effective
controller for a wide range of embedded applications.
The Flash memory can be programmed using a parallel
programmer available from Ramtron. Support is also
available from 3
rd
party commercial programmer
manufacturers.
The VMX51C900 is available in PLCC-44, QFP-44 and
DIP-40 packages and operates over the industrial
temperature range.
