SILICON LABS C8051F505-IQR

This chip features the following characteristics:

• 12-bit ADC: up to 200ksps sample rate, up to 32 external single-ended inputs, reference voltage sourced from on-chip VREF, external pin, or VDD, selectable internal or external conversion source, built-in temperature sensor.
• Two comparators: programmable hysteresis and response time, configurable as interrupt or reset source, low current.
• On-chip debug: on-chip debug circuit enables full-speed, non-intrusive in-system debugging (no emulator required), supports breakpoints, single-step execution, memory and register inspection/modification, superior to emulation systems using ICE chips, target expansion boards and sockets, low development kit cost.
• Supply voltage: 1.8 to 5.25V. Typical operating current: 19mA at 50MHz; typical stop-mode current: 2μA.
• High-speed 8051 MCU core: pipelined instruction architecture, 70% of instructions execute in 1 or 2 system clocks, peak throughput of 50MIPS at 50MHz clock, extended interrupt handlers.
• Memory: 4352 bytes internal data RAM (256 + 4096 XRAM), 64 or 32kB flash, in-system programmable in 512-byte sectors.
• Digital peripherals: 40, 33, or 25 port I/Os, all 5V-tolerant; CAN 2.0 controller, no crystal required; LIN 2.1 controller (master/slave mode), no crystal required; hardware-enhanced UART, SMBus, and enhanced SPI serial ports; four general-purpose 16-bit counter/timers; 16-bit programmable counter array (PCA) with six capture/compare modules and enhanced PWM.
• Clock sources: internal 24MHz oscillator with ±0.5% accuracy for CAN and master LIN operation; external oscillator supporting crystal, RC, C, or clock (1 or 2-pin mode), real-time clock source switching useful in power-saving modes.
• Package: 48-pin QFP/QFN (C8051F500/1/4/5), 40-pin QFN (C8051F508/9 - F510/1), 32-pin QFP/QFN (C8051F502/3/6/7).
