Infineon Technologies CY8C29466-24PVXIT

Overview

CY8C29466-24PVXIT from Infineon Technologies (formerly Cypress Semiconductor) is a programmable PSoC® 1 mixed-signal system-on-chip featuring an M8C 8-bit Harvard-architecture CPU running at up to 24 MHz, 32 KB flash, 2 KB SRAM, and configurable analog/digital blocks. It operates from 3.0 V to 5.25 V (or down to 1.0 V with on-chip switch-mode pump), supports industrial temperature range (–40 °C to +85 °C), and integrates up to four UARTs, multiple PWMs, ADCs up to 14-bit, and programmable gain amplifiers - used in embedded sensor interface and motor control subsystems.

For engineers reviewing the CY8C29466-24PVXIT datasheet, CY8C29466-24PVXIT pinout, CY8C29466-24PVXIT application, or CY8C29466-24PVXIT equivalent, key selection criteria include its 28-pin SSOP package, 24 MHz internal oscillator tolerance (±5% over full temp range), configurable GPIO drive modes (25 mA sink), analog input routing flexibility, and ISSP-based in-system programming capability.

Technical Context

The CY8C29466-24PVXIT implements a fixed-function digital system built from 16 reconfigurable 8-bit digital PSoC blocks and 12 analog PSoC blocks, interconnected via global digital/analog busing. Its M8C core executes instructions at 24 MHz with two 8×8 multiply/32-bit accumulate units and supports interrupt-driven real-time operation using a 17-vector controller.

Clocking combines a ±5% 24 MHz internal main oscillator (IMO), optional 32.768 kHz crystal for RTC/PLL-derived 24 MHz, and a low-power 32 kHz ILO for sleep/WDT. Analog resources include rail-to-rail comparators, PGA stages, switched-capacitor filters, and decimator-based ADCs with up to 14-bit effective resolution.

FAQ

Does CY8C29466-24PVXIT support in-circuit debugging without external hardware?

Yes. It supports full-speed in-circuit emulation and programming via two-wire Serial Wire Debug (SWD) using MiniProg3. No external debug probe is needed beyond the MiniProg3 programmer, which connects directly to SWDCK/SWDIO pins and provides power, reset, and clock synchronization.

What is the maximum achievable resolution for ADC conversions on this device?

The device achieves up to 14-bit effective resolution using its decimator-based successive-approximation ADC architecture with programmable gain amplifier (PGA) front-end. Resolution depends on PGA gain setting, sampling rate, and external noise; typical SNR is 80 dB at 10 kSPS with PGA gain = 1.

Can GPIO pins be used simultaneously for analog input and digital interrupt generation?

Yes. Any GPIO pin configured for analog input (e.g., P0[0]–P0[7], P1[0]–P1[7]) retains full digital functionality including interrupt-on-change, high-level, or low-level triggering - enabling hybrid signal acquisition and event-driven response in the same pin.

Is the internal 24 MHz oscillator accurate enough for UART communication at 115.2 kbps?

Yes. With ±5% tolerance over –40 °C to +85 °C, the internal main oscillator yields ±57.6 kHz error at 24 MHz, resulting in <±1.5% baud rate deviation at 115.2 kbps - well within UART receiver tolerance (typically ±3%). Auto-baud detection is not required.
