CY7C601xx, CY7C602xx
enCoRe™ II Low-Voltage Microcontroller
1. Features
■ enCoRe II low-voltage (enCoRe II LV) – enhanced
component reduction
❐ Internal crystalless oscillator with support for optional
external clock or external crystal or resonator
❐ Configurable I/O for real world interface without external
components
■ 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 random access memory (RAM)
❐ 8 KB of flash including electrically erasable read only memory
(EEROM) emulation
■ Low power consumption
❐ Typically 2.25 mA at 3 MHz
❐ 5 A sleep
■ In-system reprogrammability
❐ Enables easy firmware update
■ General-purpose I/O (GPIO) ports
❐ Up to 36 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,
configurable pull-up, open drain output, complementary
metal oxide semiconductor (CMOS), and
transistor-transistor logic (TTL) inputs, and CMOS output
❐ Maskable interrupts on all I/O pins
2. Logic Block Diagram
■ 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,
which 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 radio frequency (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 (LVD) with user-selectable threshold
voltages
■ Improved output drivers to reduce electromagnetic interference
(EMI)
■ Operating voltage from 2.7 V to 3.6 V DC
■ Operating temperature from 0 °C to 70 °C
■ Available in 40-pin plastic dual inline package (PDIP), 24-pin
small outline integrated circuit (SOIC), 24-pin quad small
outline package (QSOP) and shrink small outline package
(SSOP), 48-pin SSOP
