Product details
Overview
CY8C29666-24PVXIT from Infineon Technologies (formerly Cypress Semiconductor) is a programmable mixed-signal System-on-Chip (SoC) integrating an M8C 8-bit Harvard-architecture CPU, 32 KB flash, 2 KB SRAM, 12 analog PSoC blocks, and 16 digital PSoC 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 delivers up to 24 MHz core speed - used in embedded sensor interface and motor control subsystems requiring reconfigurable analog/digital peripherals.
For engineers reviewing the CY8C29666-24PVXIT datasheet, CY8C29666-24PVXIT pinout, CY8C29666-24PVXIT application, or CY8C29666-24PVXIT equivalent, key selection criteria include its 24 MHz IMO accuracy (±5% over full temp/voltage), configurable GPIO drive modes (25 mA sink/10 mA source), 14-bit ADC capability, I²C/SPI/UART peripheral support, and PSoC Designer-based user module customization flow.
Technical Context
The CY8C29666-24PVXIT implements a fixed-function M8C CPU core with interrupt controller (17 vectors), sleep/watchdog timers, and dual-clock domain architecture: 24/48 MHz internal main oscillator (IMO) with optional PLL-locked 24 MHz from 32.768 kHz crystal, plus 32 kHz internal low-speed oscillator (ILO) for low-power timing. Its global interconnect fabric routes signals between 8 digital blocks and 12 analog blocks across five I/O ports.
Analog resources include decimator-based 14-bit ΔΣ ADCs, 9-bit DACs, programmable gain amplifiers (PGAs), and rail-to-rail comparators; digital resources support 8–32-bit timers/counters, 8-/16-bit PWMs with dead-band, CRC/PRS modules, and up to four UARTs - all configurable via PSoC Designer's drag-and-drop user modules without hardware redesign.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | M8C 8-bit Harvard CPU, 4 MIPS @ 24 MHz - enables deterministic real-time control with separate instruction/data buses. |
| Flash Memory | 32 KB program flash with 50,000 erase/write cycles and 4-level block protection - supports secure firmware updates and IP protection. |
| SRAM | 2 KB static RAM - sufficient for real-time data buffering and stack operations in sensor fusion or motor commutation routines. |
| Analog Blocks | 12 rail-to-rail configurable analog PSoC blocks - deliver ADC (up to 14-bit), DAC (up to 9-bit), PGA, comparator, and filter functions on shared GPIO pins. |
| Digital Blocks | 16 programmable digital PSoC blocks - combine to form 8–32-bit timers, PWMs, UARTs (up to 4), SPI (master/slave), and I²C (slave/multi-master). |
| Operating Voltage | 3.0 V to 5.25 V standard; 1.0 V minimum with on-chip switch-mode pump (SMP) - enables battery-powered operation with voltage scaling. |
| Temperature Range | –40 °C to +85 °C industrial grade - validated for use in automotive body electronics and industrial HMI panels. |
Pinout & Package
Package: 44-pin Plastic Leaded Chip Carrier (PLCC), 16.59 mm × 16.59 mm, JEDEC MS-026AC compliant. Pinout validated per CY8C29666-24PVXIT datasheet Rev. AD (Page 11, "44-Pin Part Pinout").
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply input | Accepts 3.0–5.25 V; powers core, analog, and digital systems - requires local 0.1 µF bypass capacitor. |
| VSS | Ground reference | Digital/analog common ground plane - must be low-impedance connection to minimize noise coupling into analog blocks. |
| XIN / XOUT | External crystal oscillator terminals | Supports 32.768 kHz crystal for RTC or PLL reference; requires load capacitors per crystal manufacturer spec. |
| P0[0]–P0[7] | Port 0 general-purpose I/O | Configurable as analog input (8 channels), digital I/O, or analog output (4 channels); supports interrupt-on-change. |
| P1[0]–P1[7] | Port 1 general-purpose I/O | Full GPIO functionality including 25 mA sink/10 mA source drive; supports pull-up/pull-down/strong/open-drain modes. |
| SWDIO / SWCLK | Debug interface pins | Enable in-circuit programming and full-speed emulation via MiniProg3; require 10 kΩ pull-up on SWDIO. |
Key Features
| Feature | Design Value |
|---|---|
| In-system serial programming (ISSP) | Enables field firmware updates via two-wire interface without removing device from PCB - critical for production calibration and post-deployment bug fixes. |
| EEPROM emulation in flash | Up to 2 KB of nonvolatile data storage using wear-leveling algorithms - replaces external EEPROM in tamper-resistant metering and configuration storage. |
| Programmable GPIO drive modes | Eight modes per pin (pull-up, pull-down, high-Z, strong, open-drain, etc.) - eliminates need for external level shifters or bus buffers in multi-voltage system interfacing. |
| Global analog/digital interconnect | Configurable routing matrix linking all 12 analog and 16 digital blocks to any GPIO - allows dynamic peripheral reassignment without PCB redesign. |
| On-chip precision voltage reference | Internal 1.2 V ±1% bandgap reference - provides stable ADC/DAC reference independent of VDD variation, improving measurement repeatability. |
Applications
| Industrial Sensor Node | Motor Control Subsystem |
|---|---|
|
Use Scenario: Compact environmental monitoring node measuring temperature, humidity, and pressure with local signal conditioning and wireless telemetry. IC Role / Device Role / Timing Role: Central SoC managing analog sensor front-end (PGA + 14-bit ADC), digital communication (I²C to sensor ICs, UART to BLE module), and low-power scheduling via sleep timer. Use Value: Single-chip integration reduces BOM count by 6+ discrete components; programmable analog blocks eliminate external op-amp/filter ICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C29466-24PVXI | Same M8C core and PSoC 1 architecture, but with 16 KB flash and 1 KB SRAM - reduced memory capacity and fewer analog/digital blocks. | Suitable for simpler sensor nodes with single ADC channel and no UART/I²C concurrency requirements. | Select when cost sensitivity outweighs need for full peripheral set and firmware scalability. |
| CY8C27443-24PVXI | Lower-cost PSoC 1 variant with 16 KB flash, 512 B SRAM, and only 8 analog + 8 digital blocks - lacks decimator ADC and advanced PWM features. | Targeted at basic GPIO expansion or LED sequencing where analog precision or motor control is not required. | Choose only for legacy replacement in low-complexity designs; not recommended for new designs requiring >12-bit ADC or multi-channel PWM. |
Compared with CY8C29466-24PVXI and CY8C27443-24PVXI, the CY8C29666-24PVXIT provides 2× flash/SRAM, full analog block complement (enabling simultaneous multi-sensor acquisition), and hardware decimation - making it the only option among the three capable of standalone 14-bit sensor data logging with onboard filtering.

FAQ
Does CY8C29666-24PVXIT support USB connectivity?
No. The CY8C29666-24PVXIT does not include a USB physical layer or USB controller. It supports UART, SPI, and I²C interfaces for host communication. For USB connectivity, external bridge ICs (e.g., CP2102) or migration to PSoC 3/4/5LP families with native USB are required.
What development tools are required to program CY8C29666-24PVXIT?
PSoC Designer™ (free Windows IDE) is mandatory for configuring analog/digital user modules and generating C code. Programming requires MiniProg1 or MiniProg3 debuggers; MiniProg3 is recommended for full-speed emulation and ISSP. No JTAG adapter is needed - SWD interface is natively supported.
Can CY8C29666-24PVXIT operate from a single 3.3 V supply?
Yes. The device is fully specified for 3.0 V to 5.25 V operation. At 3.3 V, it achieves full 24 MHz performance with ±5% IMO accuracy and supports all analog blocks (ADC, DAC, PGA) without derating - verified per DC Electrical Characteristics table (Section 22, Rev. AD).
Is there hardware support for cryptographic functions?
No. CY8C29666-24PVXIT lacks dedicated crypto accelerators or secure key storage. Security relies on flash protection levels (4-tier block locking) and software-based AES/SHA implementations. For hardware crypto, consider Infineon's OPTIGA™ Trust series or PSoC 6 devices with ARM CryptoCell.
