8 / 35 page  CYONS2001 Document Number: 001-44045 Rev. *G Page 8 of 35 PSoC Functional Overview Cypress's programmable system-on-chip (PSoC) on-chip controllers combine dynamic, configurable analog and digital blocks and an 8-bit MCU on a single chip, replacing multiple discrete components while delivering advanced flexibility and functionality. A PSoC device includes configurable analog and digital blocks, and programmable interconnect. This architecture can create customized peripheral configurations to match the requirements of each individual application. Additionally, 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 Figure 2 on page 4, contains: the core, the navigation sensor, the power system, and the system resources. A common, versatile bus enables connection between I/O and the analog system. GPIO, which provides access to the MCU and analog mux, is also included. The PSoC Core The PSoC core is a powerful engine that supports a rich instruction set. The PSoC core encompasses SRAM for data storage, an interrupt controller, sleep and watchdog timers, an IMO, and an Internal Low Speed Oscillator ILO. The CPU core, called the M8C, is a powerful processor with speeds up to 24 MHz. The M8C is a 4 miliion instructions per second (MIPS) 8-bit Harvard architecture microprocessor. System resources provide additional capability, such as configurable USB and SPI master-slave communication interface, three 16-bit programmable timers, and various system resets supported by the M8C. The Analog Multiplexer System The analog mux bus connects to every GPIO pin. Pins are connected to the bus individually or in any combination. Analog signals may be routed to an internal ADC. Other multiplexer applications include: ■ Chip-wide mux that enables analog input from any I/O pin ■ Crosspoint connection between any I/O pin combinations Additional System Resources System resources, some 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: ■ The SPI master/slave module ❐ Provides communication over three or four wires ❐ Runs at speeds of 46.9 kHz to 3 MHz (lower for a slower system clock). ■ An I2C slave module ■ Low voltage detection (LVD) interrupts can signal the application of falling voltage levels, while the advanced POR circuit eliminates the need for a system supervisor. ■ An internal reference provides an absolute reference for capacitive sensing. Getting Started For in depth information, along with detailed programming details, see the PSoC® Technical Reference Manual.
