Cypress Introduces CY8C23x33 PSoC Mixed Signal Array for Motor Control

Cypress Semiconductor Corp. (NYSE:CY) introduced a new PSoC® mixed-signal array with an enhanced analog-to-digital converter (ADC) for fast analog sampling and expanded 8 Kbytes of Flash memory capacity for complex algorithm processing. The CY8C23x33, the newest member of Cypress’s flagship PSoC family, targets applications with rich feature and software content, ranging from motor control, to camera image engines, to powerline communications and more.

Cypress CY8C23x33 PSoC mixed-signal array with analog-to-digital converter (ADC)The PSoC mixed-signal architecture integrates programmable analog and digital blocks with an 8-bit microcontroller, a unique combination that offers designers unmatched flexibility for a variety of applications. The new CY8C23x33 device features an 8-bit successive-approximation (SAR) ADC to allow a high sampling rate of 375 Ksps. It offers 26 GPIOs to deliver a premium level of configurability to quickly adapt to changes in feature requirements. The device is available in a 5×5 mm QFN package to minimize board space.

“We can now offer a flexible, robust solution for a broad range of applications,” said Dhwani Vyas, vice president of Cypress’s PSoC products. “We are excited to extend PSoC’s trademark programmable analog capabilities to a large segment of new customers.”

The CY8C23x33 PSoC devices feature four digital blocks, including two basic and two communication blocks, and four analog blocks, including two continuous time and two switched capacitor blocks. One of the device’s digital blocks is a dedicated hardware I2C block that enables fast and easy programmability to reduce design time.

The CY8C23x33 PSoC devices are now in full production. The CY8C23533 is available in a 32-pin 5×5 mm QFN package and the CY8C23433 is available in a 28-pin SSOP package.

PSoC — Because Change Happens
PSoC devices employ a highly configurable system-on-chip architecture for embedded control design, offering a flash-based equivalent of a field-programmable ASIC without lead-time or NRE penalties. PSoC devices integrate configurable analog and digital circuits, controlled by an on-chip microcontroller, providing both enhanced design revision capability and component count savings. They include up to 32 Kbytes of Flash memory, 2 Kbytes of SRAM, an 8×8 multiplier with 32-bit accumulator, power and sleep monitoring circuits, and hardware I2C communications.

The flexible PSoC resources allow designers to future-proof their products by enabling firmware-based changes during design, validation, production, and in the field. The unique PSoC flexibility shortens design cycle time and allows for late-breaking feature enhancements. All PSoC devices are also dynamically reconfigurable, enabling designers to morph internal resources on-the-fly, utilizing fewer components to perform a given task.

Easy to use development tools enable designers to select configurable library elements for analog functions such as amplifiers, ADCs, DACs, filters and comparators and digital functions such as timers, counters, PWMs, SPI and UARTs. The PSoC family’s analog features include rail-to-rail inputs, programmable gain amplifiers and up to 14-bit ADCs with exceptionally low noise, input leakage and voltage offset.

A single PSoC device can integrate as many as 100 peripheral functions saving customers design time, board space and power consumption while improving system quality. Customers can save as much as $10 in system costs. More information about PSoC products is available at and free online training is at
