Microchip Technology Inc. expanded its 28- and 40/44-pin PIC Flash microcontroller (MCU) portfolio with eight devices targeting high-end applications requiring additional memory in low pin counts, such as industrial, computing, telecommunications and consumer apps.

The company said that the new products can help designers of embedded control applications that need 8-bit microcontrollers with increased memory in small form factors, balanced with

a requirement to consume less power.

"Microchip is seeing growing design activity in the already popular 28- and 40/44-pin space of the 8-bit microcontroller market," stated Ganesh Moorthy, VP of Microchip's Advanced Microcontroller and Memory Division. According to Moorthy, their latest Flash PIC MCUs provide the highest density memory available in low pin counts.

Features nanoWatt Technology

The devices feature 48KB or 64KB of Flash program memory, 4KB of RAM and nanoWatt Technology low-power modes.

With the nanoWatt Technology, the PIC18F2620, PIC18F2610, PIC18F2525, PIC18F2515, PIC18F4620, PIC18F4610, PIC18F4525 and PIC18F4515 MCUs offer power-managed modes that make them suitable for battery and low-power applications. They also feature the company's PMOS Electrically Erasable Cell (PEEC) Flash process technology, which enables up to 1,000,000 data memory ERASE/WRITE cycles and up to 100,000 program memory ERASE/WRITE cycles, with 40 years of data retention.

The PIC microcontroller family offers Standard Flash and Enhanced Flash. The Enhanced Flash family has self-programming capability, allowing the MCU to be programmed after being placed in a circuit board. They also contain 1KB of high-endurance EEPROM data memory.

With a voltage range of 2V to 5.5V and operating between the -40C to 125C temperature range, the devices feature an external clock with up to 40MHz (10MIPS), a 32KHz to 32MHz (8MIPS) internal oscillator, fail-safe clock monitor, In-Circuit Serial Programming (ICSP), a 10-bit ADC with up to 13 signal channels and 100k samples-per-second, and two analog comparators with programmable brownout detect and programmable low-voltage detect.

All eight MCUs are supported by Microchip's development systems, including MPLAB Integrated Development Environment (IDE), MPLAB C18 C Compiler, MPLAB SIM tool, MPLAB ICD 2 In-Circuit Debugger, and MPLAB ICE 2000 In-Circuit Emulator.

The PIC18F2620, PIC18F2610, PIC18F2525 and PIC18F2515 are available in 28-pin SDIP, SOIC, while the PIC18F4620, PIC18F4610, PIC18F4525 and PIC18F4515 are offered in 40-pin PDIP; and 44-pin TQFP, QFN.
