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 IO are
included in a range of convenient pinouts.
The architecture for this device family, as illustrated (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’ legacy low voltage microcon-
trollers include faster CPU at lower voltage operation, lower
current consumption, twice the RAM and Flash, hot-swapable
IOs, 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/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. Brief statements describing the merits of each system
resource are presented below.
• 10-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/SPI master-slave module provides 50/100/400
kHz communication over two wires. SPI communication over
3 or 4 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, 1.8/2.5/3V-selectable output,
low-dropout regulator (LDO) provides regulation for IOs. A
register-controlled bypass mode allows the user to disable the
LDO.
• Standard Cypress PSoC IDE tools are available for debugging
the enCoRe V LV family of parts.
