Microchip Technology Inc. unveils the PIC18F47J53 to expand to its 8bit and USB microcontroller (MCU) line that features the "XLP technology" for "eXtreme Low Power Consumption". The MCU offers up to 128KB flash program memory and 4KB RAM, giving plenty of code space for Microchip's free USB stack and for application code.


The MCU features full-speed USB 2.0 capability, enabling applications that can perform remote field upgrades, download usage data and connect to diagnostic equipment. The integrated mTouch sensing capability permits easy implementation of capacitive touch sensing user interfaces, while XLP technology reduces power consumption, helping to extend battery life.

Microchip also offers a free smart card library, within its free USB stack. An on-chip 12bit analogue-to-digital converter offers the accuracy needed for many advanced sensor, instrumentation and measurement applications. The MCU targets portable consumer devices, medical devices, and other applications requiring low power consumption and USB connectivity with its multiple PWMs, timers and SPI channels with DMA.

VP of Microchip's Advanced Microcontroller Architecture Division, Mitch Obolsky says, "The MCU offers a fully compatible memory extension to our popular PIC18F46J50 USB family, serving a wide spectrum of applications, such as handheld medical devices and speaker accessories for iPod."

Microchip has also announced availability of their PIC18F47J53 Full-Speed USB Demo board (part # MA180029, Rs.2,101.32 ($45)). This board can be used as a stand-alone or as plug-in to the PIC18 Explorer board (part # DM183032, Rs.4,669.14 ($99.99)). Furthermore, designers can utilise Microchip's complete suite of standard development tools with the new MCUs, including the user-friendly and free MPLAB IDE and corresponding suite of emulators, programmers and development boards, along with the MPLAB C or HI-TECH C compiler for PIC18 MCUs.

Samples and volume quantities are available now. The PIC18F27J53 MCU is available in 28-pin QFN, SOIC, SPDIP, and SSOP packages. The PIC18F47J53 MCU is likewise available in 44-pin QFN and TQFP packages. Pricing starts at Rs.107.87 ($2.31) each, in 10,000-unit quantities.
