CY8C22345H-24PVXA

Overview

The CY8C22345H-24PVXA is a member of the Cypress PSoC 1 mixed-signal array family, integrating an M8C 8-bit microcontroller core with programmable analog and digital peripherals. It features 8 kB of Flash program memory and 1 kB of SRAM data memory. The device operates at a maximum clock frequency of 24 MHz and supports a supply voltage range of 1.71 V to 5.5 V. It includes a 10-bit ADC, three timers/counters, and standard communication interfaces such as I2C and SPI. The component is housed in a 48-pin SSOP package and is rated for commercial operating temperatures.

Feature Summary

• Integrates a high-performance M8C 8-bit processor with configurable mixed-signal blocks for system-level integration.
• Supports CapSense technology for capacitive touch sensing applications without external components.
• Provides flexible analog-digital conversion capabilities through a built-in 10-bit analog-to-digital converter.

Applications

• Capacitive touch interface controllers for consumer electronics
• Battery-powered portable devices requiring low-voltage operation
• Industrial control systems utilizing mixed-signal processing

Procurement Notes

Verify the specific suffix 'H' against official Infineon or Cypress documentation to confirm temperature grade and packaging specifications. Ensure compatibility with existing firmware compiled for the M8C architecture. Confirm that the 48-pin SSOP footprint matches the target PCB design. Check for RoHS compliance status in the latest datasheet revision.

Selection Notes

Select this component when a combination of 8-bit processing, programmable analog functions, and touch sensing is required. It is suitable for designs needing a wide voltage input range and moderate performance. Consider alternative PSoC 1 variants if different pin counts or memory sizes are needed. Evaluate power consumption requirements against the 24 MHz operational speed.

Part Context

This part belongs to the PSoC 1 family, which merges digital and analog subsystems on a single chip. The CY8C22xxx series typically targets cost-sensitive applications requiring mixed-signal capabilities. It shares architectural similarities with other CY8C20xx6A and CY8C24xxx models but differs in peripheral configuration and package options.

Replacement Considerations

Direct substitutes may include other CY8C22345 variants with different suffixes indicating package or temperature changes. Cross-reference with CY8C24223 or CY8C20536 families for functional equivalents, ensuring memory and I/O pin compatibility. Verify that any replacement maintains the same M8C core instruction set.
