CY7C604XX

Functional Overview Getting Started

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.

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.
