Product details
Overview
CY8C22345-24PVXAT from Infineon Technologies (formerly Cypress) is an AEC-Q100 qualified automotive-grade PSoC® programmable system-on-chip featuring an M8C 8-bit Harvard architecture CPU running at up to 24 MHz, 16 KB flash, 1 KB SRAM, and six Type 'E' analog blocks with integrated 10-bit SAR ADC - used in body control modules, dashboard interfaces, and haptic feedback systems.
For engineers reviewing the CY8C22345-24PVXAT datasheet, CY8C22345-24PVXAT pinout, CY8C22345-24PVXAT application, or CY8C22345-24PVXAT equivalent, key selection criteria include A-grade temperature range (–40 °C to +85 °C), 3.0–5.25 V operation, CapSense® dual-channel support, Immersion® TouchSense® haptics capability, and configurable digital/analog block interconnect for custom peripheral synthesis.
Technical Context
The device implements a fixed-function M8C core with deterministic interrupt latency and ISSP-capable flash memory, paired with reconfigurable analog and digital PSoC blocks that operate on shared global interconnects. Its 10-bit SAR ADC includes sample-and-hold and supports simultaneous scanning of two CapSense channels using dedicated 16-bit timers and current DACs.
Digital resources include eight 8-bit blocks arranged in two rows (four per row), enabling synthesis of PWMs with deadband, UARTs, SPI masters/slaves, CRC generators, and PRS modules - all connectable to any GPIO via programmable routing. Analog subsystem uses CT and SC Type 'E' blocks with internal 1.3 V reference and DAC-based comparator references.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C22345-24PVXI | Same die, industrial-grade (–40 °C to +85 °C), non-AEC-Q100 qualified, same package and pinout | Lacks automotive qualification documentation and test reports; unsuitable for production in safety-critical or OEM-specified systems | Select only for prototyping or non-automotive industrial use where AEC compliance is not mandated. |
| CY8C22645-24PVXAT | Higher memory variant: 16 KB flash, 2 KB SRAM, eight digital blocks (vs. eight in CY8C22345), same analog block count and haptics engine | Supports more complex firmware (e.g., dual CAN/LIN stacks + CapSense + haptics), larger data buffers for logging or OTA updates | Choose when firmware size exceeds 16 KB or additional SRAM is needed for real-time signal processing tasks. |
Compared with CY8C22345-24PVXAT, the CY8C22345-24PVXI lacks AEC-Q100 validation and traceability for automotive production, while CY8C22645-24PVXAT offers expanded memory and digital resources - making it suitable for feature-rich variants without changing board layout or firmware architecture.

FAQ
What is the maximum operating frequency of the M8C core in CY8C22345-24PVXAT?
The M8C core operates at up to 24 MHz in A-grade devices like CY8C22345-24PVXAT, delivering 4 MIPS performance. This speed is sustained across the full –40 °C to +85 °C temperature range and 3.0–5.25 V supply, verified per AEC-Q100 stress testing protocols.
Does CY8C22345-24PVXAT support hardware-based I2C communication?
Yes - it includes a dedicated I2C master/slave/multi-master module supporting up to 400 kHz operation with hardware address detection, automatic ACK/NACK handling, and interrupt-driven transaction completion - usable without bit-banging or CPU overhead.
Can the CapSense® functionality operate independently of the CPU during sleep mode?
No - CapSense® scanning requires active CPU execution of the CapSense user module firmware. However, the device supports low-power sleep modes with wake-on-GPIO, and CapSense® can resume scanning within microseconds after wake, leveraging dedicated 16-bit timers and current DACs for fast initialization.
Is the Immersion® TouchSense® haptics engine licensed separately?
No - the TouchSense® haptics controller is fully integrated into the silicon and enabled by factory-programmed firmware. No additional license, royalty, or external configuration IC is required; all 14 ERM effects are accessible via standard PSoC Designer API calls.
