Infineon Technologies CY8C22113-24SIT

Overview

CY8C22113-24SIT from Cypress Semiconductor is an 8-bit programmable mixed-signal array (PSoC™) IC integrating M8C CPU core, 2 KB Flash, 256 B SRAM, 4 digital PSoC blocks, and 3 analog PSoC blocks in a 24-pin SOIC package. It operates at up to 24 MHz, supports rail-to-rail analog peripherals including 14-bit ADCs and 9-bit DACs, and delivers configurable GPIO with 25 mA sink and analog input/output capability - used in embedded sensor interface and motor control subsystems.

For engineers reviewing the CY8C22113-24SIT datasheet, CY8C22113-24SIT pinout, CY8C22113-24SIT application, or CY8C22113-24SIT equivalent, key selection criteria include its 24 MHz M8C core speed, 3-analog-block + 4-digital-block resource allocation, 3.0–5.25 V supply range, industrial temperature rating (−40°C to +85°C), and ISSP-based in-system programming support.

Technical Context

The CY8C22113-24SIT implements a Harvard-architecture M8C CPU running at up to 24 MHz with 10 interrupt vectors and integrated Sleep/WDT timers. Its digital system comprises four 8-bit configurable blocks supporting 8–32-bit PWMs, counters, UART, SPI, and CRC generators - all routable via global digital interconnect to any GPIO.

The analog system integrates one CT and two SC blocks enabling programmable gain amplifiers (up to 48×), 6–14-bit ADCs (Delta-Sigma/SAR/Incremental), 6–9-bit DACs, comparators with 16 thresholds, and 30 mA analog output drivers - all accessible through a shared analog mux and reference (1.3 V internal).

FAQ

Does CY8C22113-24SIT support in-system programming without removing it from the PCB?

Yes. The device supports In-System Serial Programming (ISSP) via the SWD pin and two GPIOs (XRES and SCLK), enabling firmware updates and configuration changes while soldered in-circuit. No external high-voltage programming supply is required - standard 3.3 V or 5 V VDD suffices, and the process preserves SRAM contents unless explicitly erased.

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

Yes. With the internal 24 MHz IMO (±2.5% over temperature/voltage), the UART baud rate generator achieves ±1.2% error at 115.2 kbps - well within the ±2% tolerance required for reliable RS-232 or TTL-level UART communication. For tighter tolerance, the optional 32.768 kHz crystal + PLL yields ±0.1% system clock accuracy.

What is the maximum sustained current capability of the analog output pin?

The analog output pin (P0[7]) delivers up to 30 mA continuously into resistive loads with rail-to-rail swing (0 V to VDD). Output voltage accuracy remains within ±10 mV of target over −40°C to +85°C when sourcing ≤20 mA; derating applies beyond that due to thermal limits in the SOIC package.

How many independent analog input channels can be sampled simultaneously?

Only one analog input channel can be actively converted at a time using the shared SAR/DS ADC hardware. However, the analog mux supports up to eight inputs (P0[0]–P0[7]), and sequential sampling across all eight channels at ≥10 kSPS is achievable using automatic scan mode and DMA-like result buffering in SRAM.
