enCoRe⢠II Low Voltage Microcontroller
1. Features
â enCoRe⢠II Low Voltage (enCoRe II LV)âenhanced
component reduction
â Internal crystalless oscillator with support for optional exter-
nal clock or external crystal or resonator
â Configurable IO for real world interface without external com-
ponents
â Enhanced 8-bit microcontroller
â Harvard architecture
â M8C CPU speed up to 12 MHz or sourced by an external
crystal, resonator, or clock signal
â Internal memory
â 256 bytes of RAM
â 8 Kbytes of Flash including EEROM emulation
â Low power consumption
â Typically 2.25 mA at 3 MHz
â 5 μA sleep
â In-system reprogrammability
â Allows easy firmware update
â General purpose IO ports
â Up to 36 General Purpose IO (GPIO) pins
â 2 mA source current on all GPIO pins. Configurable 8 or
50 mA per pin current sink on designated pins
â Each GPIO port supports high impedance inputs, config-
urable pull up, open drain output, CMOS and TTL inputs, and
CMOS output
â Maskable interrupts on all IO pins
â SPI serial communication
â Master or slave operation
â Configurable up to 2 Mbit per second transfers
â Supports half duplex single data line mode for optical sensors
â 2-channel 8-bit or 1-channel 16-bit capture timer registers.
Capture timer registers store both rising and falling edge times
â Two registers each for two input pins
â Separate registers for rising and falling edge capture
â Simplifies interface to RF inputs for wireless applications
â Internal low power wakeup timer during suspend mode
â Periodic wakeup with no external components
â Programmable interval timer interrupts
â Reduced RF emissions at 27 MHz and 96 MHz
â Watchdog timer (WDT)
â Low voltage detection with user selectable threshold voltages
â Improved output drivers to reduce EMI
â Operating voltage from 2.7V to 3.6V DC
â Operating temperature from 0â70°C
â Available in 24 and 40-pin PDIP, 24-pin SOIC, 24-pin QSOP
and SSOP, 28-pin SSOP, and 48-pin SSOP
â Advanced development tools based on Cypress PSoC® tools
â Industry standard programmer support
