On-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
- 2 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 six 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
Package
- 10-Pin QFN (3x3 mm)
Ordering Part Number
- C8051F526-IM
