Introduction
— Maskable interrupts on all I/O pins
• SPI serial communication
The enCoRe II LV family brings the features and benefits of the
enCoRe II to non-USB applications. The enCoRe II family has
an integrated oscillator that eliminates the external crystal or
resonator, reducing overall cost. Other external components,
such as wake-up circuitry, are also integrated into this chip.
— Master or slave operation
— Configurable up to 2-Mbit/second transfers.
— Supports half duplex single data line mode for optical
sensors
The enCoRe II LV is a low-voltage, low-cost 8-bit Flash-
programmable microcontroller
• 2-channel 8-bit or 1-channel 16-bit capture timer registers.
Capture timer registers store both rising and falling edge
times
The enCoRe II LV features up to 36 general-purpose I/O
(GPIO) pins. The I/O pins are grouped into five ports (Port 0 to
4). The pins on Port 0 and Port 1 may each be configured
individually while the pins on Ports 2, 3, and 4 may only be
configured as a group. Each GPIO port supports high-
impedance inputs, configurable pull up, open drain output,
CMOS/TTL inputs, and CMOS output with up to five pins that
support programmable drive strength of up to 50 mA sink
current. Additionally, each I/O pin can be used to generate a
GPIO interrupt to the microcontroller. Each GPIO port has its
own GPIO interrupt vector with the exception of GPIO Port 0.
GPIO Port 0 has in addition to the port interrupt vector, three
dedicated pins that have independent interrupt vectors
(P0.2–P0.4).
— 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 wake-up timer during suspend mode
— Periodic wake-up 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
