Cygnal Integrated Products announced the C8051F300, microcontroller in a tiny 3x3mm footprint. Compute capability is supplied by a pipelined 8051 CPU, delivering up to 25MIPS at 25MHz. An 8-bit 500ksps A/D Converter with integrated temperature sensor is included for data acquisition. A low power programmable analogue comparator is suitable for monitoring system voltages or as a wake-up source. Programmable counters and timers can be configured for a wide range of uses, including pulse-width modulators and a real-time clock. A 2% accurate on-chip oscillator allows the built-in UART to function without an external crystal. Also on board is 8kBytes of in-system programmable FLASH. Integrated on-chip debug circuitry eliminates the need for large profile sockets and expensive in-circuit emulators. Both development kits and chips will be available in October.
