C8051F506-IQR

The C8051F506-IQR is an 8-bit microcontroller based on the high-speed 8051 core with a pipelined architecture that executes up to 50 MIPS at 50 MHz. It integrates 32KB of in-system programmable Flash memory and 4.25KB of internal data RAM (256 + 4096 XRAM). The device includes a 12-bit ADC with up to 200 ksps sampling rate and 25 external input channels, along with two comparators and a built-in temperature sensor. Communication interfaces include SMBus (I2C), CAN 2.0, LIN 2.1, SPI, and UART/USART. Digital peripherals include a 16-bit programmable counter array (PCA) with PWM, POR, watchdog timer, and four general-purpose 16-bit timers. The microcontroller operates from 1.8V to 5.25V, drawing 19 mA typical at 50 MHz and only 2 µA in stop mode. It is available in a 32-LQFP (7x7mm) surface-mount package and rated for operation from -40°C to +125°C, making it suitable for automotive-grade applications. On-chip debug circuitry provides full-speed, non-intrusive in-system debugging without an emulator.
