PSOC™ 3

The PSOC™ architecture consists of configurable analog and digital blocks, a CPU subsystem and programmable routing and interconnect. PSOC™ lets you plug in predefined and tested IP from the PSOC™ library of functions, or code your own. Either way, you have the flexibility to build innovation and competitive advantage into your products.

Programable Routing & Interconnect:
This frees you to re-route signals to userselected pins, shedding the constraints of a fixed-peripheral controller. In addition, global buses allow for signal multiplexing and logic operations, eliminating the need for a complicated digital-logic gate design.

Configurable Analog and Digital Blocks:
The union of configurable analog and digital circuitry is the basis of the PSOC™ platform. You configure these blocks using pre-built library functions or by creating your own. By combining several digital blocks, you can create 16-, 24-, or even 32-bit wide logic resources. The analog blocks are composed of an assortment of switch capacitor, op-amp, comparator, ADC, DAC, and digital filter blocks, allowing complex analog signal flows. For a partial list of preconfigured functions included in PSOC™ software, see the sidebars on the next two pages. You can modify and personalize each function to your design.

CPU Subsystem:
PSOC™ offers a sophisticated CPU subsystem with SRAM, EE PROM, and flash memory, multiple core options and a variety of essential system resources including:

• Internal main and low-speed oscillator
• Connectivity to external crystal oscillator for precision, programmable clocking
• Sleep and watchdog timers
• Multiple clock sources that include a PLL

PSOC™ devices also have dedicated communication interfaces like I2C, Full-Speed USB 2.0, CAN 2.0, and on-chip debugging capabilities using JTAG and Serial Wire Debug. The newest members of the PSOC™ family offer industry-standard processors like the 8051 and Arm® Cortex®-M3.

Low Power Management Solutions with PSOC™ 3 and PSOC™ 5 devices are easy to design and implement because both families were designed for power optimization. PSOC™ 3 and PSOC™ 5 devices have flexible power modes to optimize power and performance.

• Best-in-class low power specifications plus industry leading CPU speed
• World’s widest voltage range, the only device that offers full analog capability below 1.8V
• Minimizes power by offloading CPU processing using on-chip programmable logic
• Integrated peripherals reduce total system level power
• PSOC™ Creator software provides easy to use APIs for quick power management
• Wide operating voltage range: 0.5V to 5.5V
• 0.8 mA at 3 MHz, 1.2 mA at 6 MHz, 6.6 mA at 48 MHz
• 1 µA sleep mode with real-time clock and low voltage detect (LVD) interrupt
• 200 nA hibernate mode with SRAM retention

Full Analog Performance Across the Entire Voltage Range

PSOC™ 3 and PSOC™ 5 are the only devices on the market to offer full analog performance down to 0.5V allowing you to not only operate off of a single cell battery, but also a solar cell.
