|Microchip Technology's PIC18F47J53 features XLP technology for extreme low power consumption. This new MCU provides up to 128KB flash program memory and 4KB RAM. This offers plenty of code space for Microchip’s free USB stack and for application code. The MCU features full-speed USB 2.0 capability, which enables applications that can perform remote field upgrades, download usage data, and connect to diagnostic equipment. These performance factors result in lower costs and more flexibility for the end user. The integrated mTouch™ sensing capability enables easy implementation of capacitive touch sensing user interfaces, while XLP technology drastically reduces the amount of power consumed and helps extend battery life. By having USB integrated on this XLP family of MCUs, there is no need to sacrifice power consumption just to have USB.
Many portable applications, such as smart card readers, occasionally need to connect to a PC or another portable device via USB. The full-speed USB 2.0 capability of the PIC18F47J53 MCU enables this, and Microchip offers a free smart card library within its free USB stack. An on-chip, 12-bit analog-to-digital converter delivers the accuracy required for many advanced sensor, instrumentation, and measurement applications. With multiple PWMs, timers, and SPI channels with DMA, the PIC18F47J53 MCU is well suited for portable consumer devices, medical devices, and other applications that require low power consumption and USB connectivity.
