C8051F53025 MIPS, 8 kB Flash, 12-Bit ADC, 20-Pin Automotive MCU

Analog Peripherals12-Bit ADC, 5 V input signal; up to 16 external inputs- ±1 LSB INL; guaranteed monotonic- Programmable throughput up to 200 ksps- Data-dependent windowed interrupt generator- Programmable gain maximizes input signal spanBuilt-in Temperature Sensor (±3 °C)One ComparatorInternal Voltage ReferencePrecision VDD Monitor/Brown-out DetectorOn-Chip Debug- On-chip debug circuitry facilitates full speed, non-intrusive in-system

debug (no emulator required)- Provides breakpoints, single stepping, watch-points- Inspect/modify memory, registers, and stack- Superior performance to emulation systems using ICE-chips, target

pods, and sockets

Supply Voltage: 2.7 to 5.25 V- Typical operating current: 7 mA at 25 MHz at 5.0 V- Multiple power saving sleep and shutdown modes

Temperature Range: –40 to +125 °C

High-Speed 8051 µC Core- Pipelined instruction architecture; executes 70% of instructions in 1 or 2

system clocks- Up to 25 MIPS throughput with 25 MHz system clock- Expanded interrupt handler

Memory- 8 kB Flash; in-system programmable; flexible security features- 256 bytes data RAM

LIN 2.0- Master or slave operation using dedicated hardware (not software imple-

mentation with UART)

Digital Peripherals- Up to 16 digital I/O; all are 5 V push-pull- Programmable 16-bit counter array with three capture/compare modules- Three general-purpose 16-bit counter/timers- Dedicated watchdog timer; bidirectional reset- Real-time clock mode using timer 3 or PCA

Clock Sources- High-precision internal programmable oscillator up to 25 MHz- External oscillator: Crystal, RC, C, or Clock

Packages- 20-Pin TSSOP and 20-Pin QFN (4x4 mm)

Ordering Part Numbers- C8051F530-IT (TSSOP)- C8051F530-IM (QFN)
