Product details
Overview
CY8C29466-24PVXA from Infineon (formerly Cypress) is a PSoC™ 1 programmable system-on-chip integrating an 8-bit M8C CPU, configurable analog and digital blocks, 32 KB flash, 2 KB SRAM, and CapSense™ capacitive sensing capability. It operates at up to 24 MHz, supports 5 V operation, and includes 28 I/O pins with programmable drive strength and interrupt-on-change. It is used in human-interface applications such as touch-button control panels in industrial HMIs and appliance control systems.
For engineers reviewing the CY8C29466-24PVXA datasheet, CY8C29466-24PVXA pinout, CY8C29466-24PVXA application, or CY8C29466-24PVXA equivalent, key selection criteria include its integrated CapSense™ engine, 5 V tolerant I/O, on-chip voltage regulator, flash reprogrammability in-system, and support for analog signal acquisition via configurable op-amps and ADCs.
Technical Context
The CY8C29466-24PVXA implements a mixed-signal architecture where analog blocks (including PGA, comparator, and 10-bit SAR ADC) and digital blocks (UDB-based PLD, timers, PWM, SPI/I²C/UART) are routed through a programmable interconnect matrix. Its M8C core executes instructions from on-chip flash with zero-wait-state access at 24 MHz.
CapSense™ functionality is implemented in hardware using dedicated IDACs and scanning logic, enabling robust touch detection without host CPU overhead. The device includes a precision internal reference (1.2 V ±1%) and supports external crystal or ceramic resonator clock sources up to 24 MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What programming tools are required for CY8C29466-24PVXA?
The CY8C29466-24PVXA is programmed using PSoC™ Designer IDE v5.4 or later, which provides graphical configuration of analog/digital blocks and C-code development for the M8C core. Programming requires a MiniProg1 or MiniProg3 programmer/debugger connected via SWD interface; no external JTAG adapter is needed.
Does CY8C29466-24PVXA support USB or CAN interfaces?
No, CY8C29466-24PVXA does not include native USB or CAN transceivers or protocol stacks. It supports UART, SPI, and I²C via its Universal Digital Blocks, but external PHYs are required for USB or CAN physical layer connectivity. Its architecture predates integrated USB/CAN in later PSoC generations.
Can CY8C29466-24PVXA operate from a 3.3 V supply?
No, CY8C29466-24PVXA is specified only for 5 V operation (4.75–5.25 V). Its internal regulator, I/O voltage thresholds, and analog reference are optimized for 5 V. Attempting 3.3 V operation results in undefined behavior, failed CapSense™ scanning, and potential flash corruption during programming.
How is CapSense™ performance affected by PCB layout?
CapSense™ accuracy depends critically on guard ring implementation, electrode trace width/spacing, and ground plane separation. Recommended layout includes 10-mil-wide electrodes, 20-mil guard ring surrounding each electrode, and uninterrupted ground plane beneath the sensor layer. Layout deviations cause sensitivity loss or false triggers, especially near metal enclosures or display cables.
