Infineon Technologies CY8C22213-24SI

Overview

CY8C22213-24SI from Cypress Semiconductor is a programmable mixed-signal array (PSoC™) integrating an M8C 8-bit Harvard CPU, 2 KB Flash, 256 bytes SRAM, 4 digital PSoC blocks, and 3 analog PSoC blocks in a 28-pin SOIC package. It operates from 3.0–5.25 V at up to 24 MHz, supports rail-to-rail analog peripherals including 14-bit ADCs and 9-bit DACs, and targets embedded control systems requiring configurable analog/digital signal processing on a single chip.

For engineers reviewing the CY8C22213-24SI datasheet, CY8C22213-24SI pinout, CY8C22213-24SI application, or CY8C22213-24SI equivalent, key selection criteria include its 24 MHz M8C core speed, 3-analog/4-digital block architecture, 8 GPIO analog inputs, 1 analog output with 30 mA drive, and support for I²C, SPI, UART, and PWM-based motor/sensor interfaces.

Technical Context

The CY8C22213-24SI implements a fully configurable mixed-signal architecture with dedicated global digital and analog interconnects linking its 4 digital blocks (each 8-bit, combinable into 8–32-bit peripherals) and 3 analog blocks (1 CT + 2 SC). Its M8C core executes at up to 24 MHz with 10 interrupt vectors and integrated Sleep/WDT timers.

Analog resources include a 1.3 V internal reference, programmable gain amplifiers (up to 48×), 16-threshold comparators, and decimator-based Delta-Sigma ADC configurations. Digital resources support full-duplex UART, SPI master/slave, CRC/PRS, and 8–32-bit timers with dead-band PWM - all routable to any of its 16 GPIO pins via flexible pin-drive modes.

FAQ

Does CY8C22213-24SI support in-system programming (ISP) without external hardware?

Yes. CY8C22213-24SI supports In-System Serial Programming (ISSP™) via dedicated pins (SDA/SCL or dedicated ISSP lines depending on configuration), enabling firmware updates through a simple 4-wire interface without removing the device from the board. The PSoC Designer IDE generates compatible hex files and handles security lock bits during programming.

Can the internal 24 MHz oscillator meet timing requirements for UART communication at 115.2 kbps?

Yes. The internal main oscillator (IMO) is specified at ±2.5% accuracy over temperature and voltage, which is sufficient for UART operation up to 115.2 kbps at 3.3 V or 5 V supply. For higher reliability in noisy environments, the optional 32.768 kHz crystal + PLL can generate a crystal-accurate 24 MHz clock, reducing bit error rate in long cable runs.

How many independent PWM channels can be generated simultaneously on CY8C22213-24SI?

Up to eight independent 8-bit PWM channels can be generated simultaneously using the four digital PSoC blocks - each block supports one 8-bit PWM, and two blocks can be cascaded to form a single 16-bit channel. All PWM outputs are fully routable to any of the 16 GPIO pins, with configurable dead-band insertion supported in software-defined modules.

Is there hardware support for Delta-Sigma ADC conversion, or is it implemented in firmware?

The decimator module is a dedicated hardware block that performs digital filtering for Delta-Sigma ADCs - it accepts oversampled bitstream input from the sigma-delta modulator (implemented in analog blocks) and outputs filtered digital data. This offloads the M8C core and enables continuous 12–14-bit conversions at up to 10 kSPS without CPU intervention.
