The venerable 8051 gets a leg up with the 20-MHz AT89LP family, which is pin-compatible with the AT89C family. The AT89LP has a wide operating voltage range of 2.0 to 5.5 V. Peripherals include a 10-bit analog-to-digital converter, an analog comparator,

The venerable 8051 gets a leg up with the 20-MHz AT89LP family, which is pin-compatible with the AT89C family. The AT89LP has a wide operating voltage range of 2.0 to 5.5 V. Peripherals include a 10-bit analog-to-digital converter, an analog comparator, pulse-width modulators, a programmable watchdog timer, and enhanced UART. They also have an internal RC oscillator. The chips are well suited for power management and motor control. They're available in 20-pin PDIP, TSSOP, and SOIC packages. Pricing for the AT89LP family starts at $0.85.
