The 80L52/54/58 and 87L52/54/58 are CHMOS low voltage(3V) 8-bit microcontrollers.IC numbers ending with digits 52 contain 8K ROM/OTPROM and 256 bytes RAM,IC numbers ending with digits 54 contain 16K ROM/OTPROM and IC numbers ending with digits 58 contain 32K ROM/OTPROM.
87L51FA,83L51FA,80L51FA,8751LFB,83L51FB,87L51FC and 83L51FC are low voltage (3V) microcontrollers having pulse-width modulation and watchdog timer features.
87C51GB,83C51GB,80C51GB,etc.are provide with 8K ROM/OTPROM,256 bytes of RAM,on-chip A/D converter,pulse width modulation,high-speed I/O,up/down counting capabilities and memory protection features.They are also provide with more versatile serial channel that facilitates multi-processor communications.
The 83C51KB is a high performance keyboard microcontroller for standard and advanced desktop computers.It uses CHMOS semiconductor technology and operates at 5V dc.It contains 4KB on-chip ROM and 128 bytes on-chip RAM.Its important features are:direct drive LED outputs,20pF cap on-chip for RC resonator （frequency selectable,4-6MHz）,8 dedicated key scan input(KSI) pins (schmitt-triger inputs,external inputs,level detect interrupt mode for automatic power-down exit),16 dedicated key scan output (KSO) pins with quasi-bidirectional port drivers (no external resistor required),configurable timer (16-bit or 2-by 8-bit),clock/data drivers to motherboard (selectable external interrupt for clock,8 x 12 compatible interface,etc.),power-on reset mode,on-chip emulation,etc.
80C51SL,87C51SL and 83C51SL are low voltage (3.3V) keyboard controllers.These are designed for keyboard control in laptop and notebook PCs.
