The C8051F021 microcontroller from Quarktwin Technology Ltd. is an 8-bit device featuring a high-speed 8051 CPU core capable of executing instructions at up to 25 MIPS with a 25 MHz clock. It includes 64 KB of in-system programmable FLASH memory and 4352 bytes of internal SRAM. The microcontroller supports a variety of digital and analog peripherals, including a 10-bit ADC with a throughput of up to 100 ksps, two 12-bit DACs, and multiple serial communication interfaces such as UART, SPI, and SMBus. It also features on-chip JTAG debugging capabilities, allowing for non-intrusive in-circuit debugging. The device operates within a supply voltage range of 2.7V to 3.6V and is available in both 100-pin and 64-pin TQFP packages, with a temperature range of -40¬8C to +85¬8C. This microcontroller is suitable for applications requiring robust performance and extensive peripheral support.
The C8051F00x-01x family devices are highly integrated mixed-signal MCUs featuring a true 10 or 12-bit multi-channel ADC and two separate 12-bit DACs, two voltage comparators (F002/07/12/17 have one only), a voltage reference, and an 8051-compatible microcontroller core with 32 kB of FLASH memory. There are also I2C/SMBus, UART, and SPI serial interfaces implemented in hardware as well as a Programmable Counter/Timer Array (PCA) with five capture/compare modules. As well as four general-purpose 16-bit timers and 4 byte-wide general-purpose digital Port I/O. The F000/01/02/10/11/12 have 256 bytes of RAM and execute up to 20 MIPS, while the F005/06/07/15/16/17 have 2304 bytes of RAM and execute up to 25 MIPS.
With an on-board VDD monitor, WDT, and clock oscillator, the MCUs are truly stand-alone System-on-a-Chip solutions. Each MCU effectively configures and manages the analog and digital peripherals. The FLASH memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. Additionally, each MCU can individually shut down any or all of the peripherals to conserve power.
