Overview
1.1 Features
• Operating voltage range: 3.0V~5.5V at -40°C~85°C (industrial)
• Operating frequency range (base on 2 clocks):
Only IRC: 16 MHz, 8 MHz, 4 MHz
* RC mode: DC ~ 16 MHz/2clks, 4.5V; DC ~ 8 MHz/2clks @ 3V
* Accuracy of IRC frequency for 4 MHz, 8 MHz and 16 MHz is at ± 2.5% at 25
o
C
• Low power consumption:
* Less than 3 mA at 5V / 4 MHz
* Typically 2 μA, during sleep mode
• 4K × 13 bits on-chip ROM
• 208 × 8 bits on-chip registers (SRAM)
• 3 bidirectional I/O ports
• 8-level stacks for subroutine nesting
• 2 programmable Level Voltage Reset (LVR): 4V, 3.3V
• 8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt
• (11+1)-bit multi-channel Analog-to-Digital Converter with 12-bit resolution (1 channel is connected
internally to OPout) for the 24-pin package
