C8051F580-IQR

The C8051F580-IQR is a high-performance 8-bit microcontroller from Silicon Laboratories based on the 8051 core. It operates at up to 50 MHz and features 128KB of banked flash memory (programmable in 512-byte sectors) and 8.25KB of internal data RAM (256 + 8192 bytes XRAM). The device includes a 12-bit ADC with up to 200 ksps sampling rate and 32 single-ended inputs, three comparators, and a built-in temperature sensor.

For connectivity, the MCU integrates a CAN 2.0 controller, a LIN 2.1 controller (master/slave), two enhanced UARTs, SMBus/I2C, and SPI interfaces. It also provides six 16-bit timers, two programmable counter arrays (PCA) with enhanced PWM, and 40 general-purpose I/O pins that are 5V tolerant with high sink current. The internal oscillator runs at 24 MHz with ±0.5% accuracy, and external clock sources are supported.

The C8051F580-IQR is automotive qualified with an operating temperature range of -40°C to 125°C and a supply voltage range of 1.8V to 5.25V. Typical operating current is 15 mA at 50 MHz, and stop mode current is 230 µA. The device is housed in a 48-TQFP (7x7 mm) surface-mount package and includes on-chip debug circuitry for non-intrusive in-system debugging.
