The PIC24FJ256GA705-I/PT from Microchip is a 16bit general purpose microcontroller with 256Kbyte flash and 16Kbyte RAM in 48 pin TQFP package. It offers various power down modes to keep the currents very low. The device features in-circuit serial programming (ICSP) and in-circuit emulation (ICE) via two pins, power-on reset (POR), brown-out reset (BOR) and oscillator start-up timer (OST), programmable low voltage detect (LVD), flexible watchdog timer (WDT) with its own RC oscillator for reliable operation. This microcontroller has three 16bit timers, two I2C, three variable width SPI, two LIN-USART/IrDA, twelve EPMP (address/data line), two configurable logic cell (CLC), real time clock and calendar (RTCC) and JTAG interfaces. Sleep and idle modes selectively shut down peripherals and/or core for substantial power reduction and fast wake-up.
