C8051F221
25 MIPS, 8 kB Flash, 8-Bit ADC, 32-Pin Mixed-Signal MCU
Analog Peripherals
8-Bit ADC
- ±1/2 LSB INL; no missing codes
- Programmable throughput up to 100 ksps
- 32 external inputs (each port I/O can be configured as an ADC input on-
the-fly)
- Programmable amplifier gain: 16, 8, 4, 2, 1, 0.5
- Data-dependent windowed interrupt generator
- VREF from external pin or VDD
Two comparators
- Programmable hysteresis
- Configurable to generate interrupts or reset
VDD Monitor and Brown-out Detector
On-Chip JTAG Debug
www.DataSheet4U- .cOonm-chip emulation circuitry facilitates full-speed, non-intrusive, in-circuit
emulation
- Supports breakpoints, single stepping, watchpoints, inspect/modify
memory, and registers
- Superior performance to emulation systems using ICE-chips, target
pods, and sockets
- Fully compliant with IEEE 1149.1 specification
Supply Voltage: 2.7 to 3.6 V
- Typical operating current: 9 mA at 25 MHz
- Typical stop mode current: <0.1 uA
Temperature Range: –40 to +85 °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; up to 21 interrupt sources
Memory
- 256 bytes data RAM
- 8 kB Flash; in-system programmable in 512 byte sectors (512 bytes are
reserved)
Digital Peripherals
- 22 port I/O; all are 5 V tolerant
- Hardware SPI™ and UART serial ports available concurrently
- 3 general-purpose 16-bit counter/timers
- Dedicated watchdog timer; bidirectional reset
Clock Sources
- Internal programmable oscillator: 2–16 MHz
- External oscillator: Crystal, RC, C, or Clock
- Can switch between clock sources on-the-fly
Package
- 32-pin LQFP (standard lead and lead-free packages)
Ordering Part Numbers
- Lead-free package: C8051F221-GQ
- Standard package: C8051F221
