1. Features
enCoRe II Low Voltage (enCoRe II LV)—enhanced
component reduction
Internal crystalless oscillator with support for optional exter-
nal clock or external crystal or resonator
Configurable IO for real world interface without external com-
ponents
Enhanced 8-bit microcontroller
Harvard architecture
M8C CPU speed up to 12 MHz or sourced by an external
crystal, resonator, or clock signal
Internal memory
256 bytes of RAM
8 Kbytes of Flash including EEROM emulation
Low power consumption
Typically 2.25 mA at 3 MHz
5 μA sleep
In-system reprogrammability
Allows easy firmware update
General purpose IO ports
Up to 36 General Purpose IO (GPIO) pins
2 mA source current on all GPIO pins. Configurable 8 or
50 mA per pin current sink on designated pins
Each GPIO port supports high impedance inputs, config-
urable pull up, open drain output, CMOS and TTL inputs, and
CMOS output
Maskable interrupts on all IO pins
SPI serial communication
Master or slave operation
Configurable up to 2 Mbit per second transfers
Supports half duplex single data line mode for optical sensors
2-channel 8-bit or 1-channel 16-bit capture timer registers.
Capture timer registers store both rising and falling edge times
Two registers each for two input pins
Separate registers for rising and falling edge capture
Simplifies interface to RF inputs for wireless applications
Internal low power wakeup timer during suspend mode
Periodic wakeup with no external components
Programmable interval timer interrupts
Reduced RF emissions at 27 MHz and 96 MHz
Watchdog timer (WDT)
Low voltage detection with user selectable threshold voltages
Improved output drivers to reduce EMI
Operating voltage from 2.7V to 3.6V DC
Operating temperature from 0–70°C
Available in 24 and 40-pin PDIP, 24-pin SOIC, 24-pin QSOP
and SSOP, 28-pin SSOP, and 48-pin SSOP
