C8051F91x-C8051F90x
Single/Dual Battery, 0.9–3.6 V, 16–8 kB, SmaRTClock, 12/10-Bit ADC MCU
Ultra-Low Power
- 160 uA/MHz in active mode (24.5 MHz clock)
- 2 us wake-up time (two-cell mode)
- 10 nA sleep mode with memory retention;
- 50 nA sleep mode with brownout detector
- 300 nA sleep mode with LFO (‘F912/02 only)
- 600 nA sleep mode with external crystal
Supply Voltage 0.9 to 3.6 V
- One-cell mode supports 0.9 to 1.8 V operation
(‘F911/01). ‘F912 and ‘F902 devices can operate
from 0.9 to 3.6 V continuously
- Two-cell mode supports 1.8 to 3.6 V operation
- Built-in dc-dc converter with 1.8 to 3.3 V output for
use in one-cell mode
- Built-in LDO regulator allows a high analog supply
voltage and low digital core voltage
- 2 built in supply monitors (brownout detectors)
12-Bit or 10-Bit Analog to Digital Converter
- ±1 LSB INL (10-bit mode); ±1.5 LSB INL (12-bit
mode, ‘F912/02 only) no missing codes
- Programmable throughput up to 300 ksps (10-Bit
Mode) or 75 ksps (12-bit mode, ‘F912/02 only)
- Up to 15 external inputs
- On-chip voltage reference
- On-Chip PGA allows measuring voltages up to twice
the reference voltage
- 16-bit auto-averaging accumulator with burst mode
provides increased ADC resolution
- Data dependent windowed interrupt generator
- Built-in temperature sensor
Two Comparators
- Programmable hysteresis and response time
- Configurable as wake-up or reset source
- Up to 15 Capacitive Touch Sense Inputs
6-Bit Programmable Current Reference
- Up to ±500 µA. Can be used as a bias or for
generating a custom reference voltage
- PWM enhanced mode on ‘F912/02 devices
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 clock
- Expanded interrupt handler
Memory
- 768 bytes RAM
- 16 kB (‘F912/1), or 8 kB (‘F902/1) Flash; In-system
programmable
Digital Peripherals
- 16 port I/O; All 5 V tolerant with high sink
current and programmable drive strength
- Hardware SMBus™ (I2C™ Compatible), 2 x SPI™,
and UART serial ports available concurrently
- Four general purpose 16-bit counter/timers
- Programmable 16-bit counter/timer array with six
capture/compare modules and watchdog timer
Clock Sources
- Internal oscillators: 24.5 MHz, 2% accuracy
supports UART operation; 20 MHz low power
oscillator requires very little bias current.
- External oscillator: Crystal, RC, C, or CMOS clock
- SmaRTClock oscillator: 32 kHz crystal or internal
low frequency oscillator (‘F912/02) or self-oscillate
mode
- Can switch between clock sources on-the-fly; useful
in implementing various power saving modes
On-Chip Debug
- On-chip debug circuitry facilitates full-speed, non-
intrusive in-system debug (no emulator required)
- Provides 4 breakpoints, single stepping
- Inspect/modify memory and registers
- Complete development kit
Packages
- 24-pin QFN (4 x 4 mm)
- 24-pin QSOP (easy to hand-solder)
- Tested die available
Temperature Range: –40 to +85 °C
