Microchip announces eight new members of its PIC24F 16-bit microcontroller family, with up to 64 Kbytes of Flash program memory and up to 8 Kbytes of RAM, in smaller, lower cost, 28- and 44-pin packages including a tiny 6x6 mm 28-pin QFN package option. The 28 and 44-pin PIC24FJ64GA004 family contains a similar peripheral set to the 100-pin PIC24FJ128GA family. “Peripheral Pin Select” pin-mapping allows designers to use the available pins exactly as they like. For many applications, this can allow the use of a smaller, more cost-effective microcontroller. The wide range of on-board peripherals includes two independent channels each of I2C UART and SPI communications.

The new devices support simple migration from a 16 MIPS PIC24F microcontroller all the way up to a 40 MIPS dsPIC33 digital signal controller.

The new PIC24FJ64GA004 family is supported by the MPLAB® Integrated Development Environment - including the enhanced Visual Device Initializer, which graphically assists the “Peripheral Pin Select” feature, generating the required initialisation code. The MPLAB C30 C compiler provides industry-leading code densities, along with free maths and peripheral libraries. For emulation and debugging with the new family, Microchip offers the MPLAB REAL ICE and the cost-effective MPLAB ICD 2.

In addition, a new version of the Explorer 16 development board is available, fitted with a 44-pin PIC24FJ64GA004 (part number DM240002). For those who already own the Explorer 16 board, a new Plug-in Module (PIM) has been created (part number MA240013) to enable development with the new family. A number of PICtail Plus daughter cards are also available for use with the Explorer 16 board that enable designers to add Ethernet connectivity, an SD/MMC card, speech playback or an IrDA® interface.
