Microchip technology has come up with 30 new 28- and 44-pin 16-bit devices for embedded system designers requiring increased memory or performance, or enhanced peripherals, while obtaining the cost and size savings associated with lower pin count devices.
The devices include ten pic24h family 40mips 16-bit microcontrollers, ten dspic33 family general-purpose digital signal controllers [dscs] and ten dspic33 motor control and power conversion family dscs. These 28- and 44-pin devices offer 32, 64 or 128 kb of programmable flash memory, up to 2 kb of dual-port ram, 4 to 16 kb of sram including dma, two on-chip comparators, a user-selectable 10-bit or 12-bit analogue-to-digital converter, a real-time clock and calendar. Standard serial peripherals include two spis, two uarts and one i2c module.
