Functional Overview
The enCoRe V LV family of devices are designed to replace
multiple traditional low voltage microcontroller system compo-
nents with one, low cost single chip programmable component.
Communication peripherals (I2C/SPI), a fast CPU, Flash
program memory, SRAM data memory, and configurable I/O are
included in a range of convenient pinouts.
The architecture for this device family, as illustrated in enCoRe
V LV Block Diagram, is comprised of two main areas: the CPU
core and the system resources. Depending on the enCoRe V LV
package, up to 36 general purpose IO (GPIO) are also included.
Enhancements over the Cypress’s legacy low voltage microcon-
trollers include faster CPU at lower voltage operation, lower
current consumption, twice the RAM and Flash, hot-swapable
I/Os, I2C hardware address recognition, new very low current
sleep mode, and new package options.

The enCoRe V LV Core

The enCoRe V LV Core is a powerful engine that supports a rich
instruction set. It encompasses SRAM for data storage, an
interrupt controller, sleep and watchdog timers, and IMO
(internal main oscillator) and ILO (internal low speed oscillator).
The CPU core, called the M8C, is a powerful processor with
speeds up to 24 MHz. The M8C is a four-MIPS, 8-bit Harvard
architecture microprocessor.
System Resources provide additional capability, such as a
configurable I2C slave and SPI master-slave communication
interface and various system resets supported by the M8C.

Additional System Resources

System Resources, some of which have been previously listed,
provide additional capability useful to complete systems.
Additional resources include low voltage detection and power on
reset. The following statements describe the merits of each
system resource:
■8-bit on-chip ADC shared between System Performance
manager (used to calculate parameters based on temperature
for flash write operations) and the user.
■The I2C slave and SPI master-slave module provides 50, 100,
or 400 kHz communication over two wires. SPI communication
over three or four wires runs at speeds of 46.9 kHz to 3 MHz
(lower for a slower system clock).
■In I2C slave mode, the hardware address recognition feature
reduces the already low power consumption by eliminating the
need for CPU intervention until a packet addressed to the target
device has been received.
■Low Voltage Detection (LVD) interrupts can signal the appli-
cation of falling voltage levels, while the advanced POR (Power
On Reset) circuit eliminates the need for a system supervisor.
■The 5V maximum input, 1.8, 2.5, or 3V selectable output, low
dropout regulator (LDO) provides regulation for I/Os. A register
controlled bypass mode enables the user to disable the LDO.
■Standard Cypress PSoC IDE tools are available for debugging
the enCoRe V LV family of parts.
Getting Started
The quickest way to understanding the enCoRe V silicon is by
reading this data sheet and using the PSoC Designer Integrated
Development Environment (IDE). This data sheet is an overview
of the enCoRe V integrated circuit and presents specific pin,
register, and electrical specifications. For in-depth information,
along with detailed programming information, reference the
PSoC Programmable System-on-Chip Technical Reference
Manual, for CY8C28xxx PSoC devices.
