C8051F305
25 MIPS, 2 kB Flash, 11-Pin Mixed-Signal MCU
Analog Peripherals
High-Speed 8051 µC Core
-
Comparator
-
Programmable hysteresis and response time
Configurable to generate interrupts or reset
Low current (0.4 µA)
-
POR/Brown-Out Detector
Memory
On-Chip Debug
-
On-chip debug circuitry facilitates full speed, non-intrusive in-system
debug (no emulator required)
Provides breakpoints, single stepping, watchpoints
Inspect/modify memory, registers, and stack
Superior performance to emulation systems using ICE-chips, target
pods, and sockets
Supply Voltage: 2.7 to 3.6 V
-
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
-
Digital Peripherals
-
Typical operating current: 5.8 mA at 25 MHz
11 µA at 32 kHz
Typical stop mode current: <0.1 µA
-
Temperature Range: –40 to +85 °C
256 bytes data RAM
2 kB Flash; in-system programmable in 512 byte sectors (512 bytes are
reserved)
8 port I/O; all are 5 V tolerant
Enhanced Hardware SMBus™ (I2C™ compatible) and UART serial
ports
Programmable 16-bit counter/timer array with three capture/compare
modules, WDT
3 general-purpose 16-bit counter/timers
Dedicated watchdog timer; bidirectional reset
Real-time clock mode using PCA or timer and external clock source
Clock Sources
-
Internal oscillator: 20 MHz nominal
