C8051F930-GDI
Tested Single/Dual Battery, 0.9–3.6 V, 64 kB Flash,
SmaRTClock, 10-Bit ADC MCU Die in Wafer Form
Supply Voltage 0.9 to 3.6 V
- One-Cell Mode supports 0.9 to 1.8 V operation
- 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)
10-Bit Analog to Digital Converter
- 1LSB INL; no missing codes
- Programmable throughput up to 300 ksps
- 23 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
- 23 Capacitive Touch Sense inputs
6-Bit Programmable Current Reference
- Up to ± 500 A. Can be used as a bias or for gener-
ating a custom reference voltage
On-Chip Debug
- On-chip debug circuitry facilitates full-speed, non-
intrusive in-system debug (no emulator required)
- Provides breakpoints, single stepping
- Inspect/modify memory and registers
- Complete development kit
High-Speed 8051 C Core
- Pipelined instruction architecture; executes 70% of
instructions in 1 to 2 system clocks
- 25 MIPS throughput with 25 MHz clock
- Expanded interrupt handler
Memory
- 4352 bytes internal data RAM (256+4096)
- 64 kB Flash; In-system programmable in 1024-byte
sectors--1024 bytes are reserved in the 64 kB
devices
Digital Peripherals
- 24 port I/O; All 5 V tolerant with high sink current
and programmable drive strength
- Hardware SMBusTM (I2C Compatible), 2 x SPITM,
and UART serial ports available concurrently
- Four general purpose 16-bit counter/timer array with
six capture/compare modules and watchdog timer
- Hardware SmaRTClock operates down to 0.9V and
requires less than 0.5 A supply current
Clock Sources
- Internal oscillators: 24.5 MHz, 2% accuracy sup-
ports UART operation; 20 MHz low power oscillator
requires very little bias current
- External oscillator: Crystal, RC, C, or CMOS Clock
- SmaRT Clock oscillator: 32 kHz Crystal or internal
self-oscillate mode
- Can switch between clock sources on-the-fly; useful
in implementing various power saving modes
Temperature range: –40 to +85 oC
