ADC resolutions range from 10 to 24 bits and CPU throughputs range from 20 to 100 MIPS. Other on-chip analog peripherals include DACs (resolutions to 12-bits), a voltage reference, comparators, a temperature sensor and oscillators. Digital peripherals include external memory interface, timers, programmable counter array (PCA) modules, and UART, SPI and SMBus serial ports. Precision analog, blazing compute speed and high integration make the Precision Mixed-Signal family a perfect choice for advanced mixed-signal systems.

Fully-specified, on-chip ADCs outperform discrete solutions, eliminating the need for external ADCs and DACs. On-chip input diff amps and voltage references further reduce solution size and cost. Other features such as programmable conversion speed, hardware window detections and programmable trigger source give designers the tools to optimize system performance.

The secure on-board Flash is programmable in-circuit with blocks segmented in 512 byte sectors (1 kB for C8051F120) and requires no special off-chip programming voltage. Software-writable Flash eliminates the cost and overhead of EEPROM.
