The 8XL5X and 8XL51FX are redesigned 3V versions of the MCS® 51 microcontroller family. Operating Vcc ranges from 2.7V to 3.6V, and maximum frequency of 20 MHz, provide both low-voltage and high- performance benefits. They provide a compatible and ideal low-voltage migration path for customers who want to design low-power versions of their embedded designs.

FEATURES	BENEFITS
Redesigned true 3V operation	Performance. High performance and low noise
Optimized for high performance (max frequency of 20 MHz)	No sacrifice. No performance loss at low voltage
Functionally compatible with other MCS® 51 microcontrollers	Easy migration. From 5V to 3V designs
Power-saving modes (idle and power down)	Power control. Improved power management control
On-chip peripherals (timer/counters, serial ports, PCA, etc.)	Integration. High integration enables low-cost and low-chip-count designs.
