Microchip has introduced two high-density 8-bit microcontrollers (MCUs) for advanced sensor, instrumentation and measurement applications.

The PIC18F47J13 and PIC18F47J53 MCUs combine XLP technology for extreme low power consumption with 128Kb Flash programme memory and 4Kb RAM, providing designers with space to implement application-specific code.

The PIC18F47J13 8-bit MCU offers 128Kb Flash programme memory in a 28-pin package, while the 44-pin PIC18F47J53 provides full-speed USB 2.0 with Microchip’s free USB stack.

Both devices integrate Mtouch technology for capacitive touch-sensing user interfaces as well as an on-chip 12-bit ADC, which provides the accuracy required by advanced sensor, instrumentation and measurement applications.

By combining a new benchmark for high memory density in a 28-pin device, with sleep currents down to 9nA and flexible wake-up sources, the PIC18F47J13 MCU extends battery life while providing generous code space and a robust peripheral set, according to the company.

This helps designers to create more efficient battery-controlled applications such as security systems, irrigation systems, remote controls, video-game controllers, wireless sensor networks and portable medical devices.

As a fully compatible memory extension to the PIC18F46J50 USB range, the PIC18F47J53 helps designers to reduce costs and provides greater flexibility for end users in consumer, medical and other portable devices.

The free Microchip USB stack, with an integrated smart-card library, enables remote field upgrades, the downloads of usage data and remote connection to diagnostic equipment.

The PIC18F47J13 MCU is supported by the PIC18 Explorer Board (part DM183032, USD99.99) and the PIC18F47J13 Plug-In Module (part MA180030, USD25).

The PIC18F47J53 Full-Speed USB Demo Board (part MA180029, USD45) can be used as a standalone development board or as a plug-in to the PIC18 Explorer Board.

Package options for the PIC18F47J13 MCU are 28-pin QFN, SOIC, SPDIP and SSOP, as well as 44-pin QFN and TQFP.

The PIC18F27J53 MCU is available in 28-pin QFN, SOIC, SPDIP and SSOP packages.

The PIC18F47J53 MCU is available in 44-pin QFN and TQFP packages.
