enCoRe™ II Low Voltage Microcontroller

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

■Advanced development tools based on Cypress PSoC® tools

■Industry standard programmer support
