Infineon Technologies CY8C29466-24PVXI

Overview

CY8C29466-24PVXI from Infineon Technologies (formerly Cypress Semiconductor) is a PSoC® 1 programmable system-on-chip integrating an M8C 8-bit Harvard-architecture CPU, 32 KB flash, 2 KB SRAM, and configurable analog/digital blocks. It operates at up to 24 MHz with 3.0–5.25 V supply, supports industrial temperature range (–40 °C to +85 °C), and delivers rail-to-rail analog functionality including 14-bit ADCs and 9-bit DACs - used in embedded sensor interface and motor control subsystems.

For engineers reviewing the CY8C29466-24PVXI datasheet, CY8C29466-24PVXI pinout, CY8C29466-24PVXI application, or CY8C29466-24PVXI equivalent, key selection criteria include its programmable analog block routing, 25-mA GPIO sink capability, ±5% internal oscillator tolerance (±2.5% at 0–70 °C), and ISSP-based in-system programming support.

Technical Context

The device implements a fixed-function M8C core with 17-interrupt-vector controller and dual-clock domain: 24/48 MHz IMO (±5% over full temp/voltage) plus 32.768 kHz ECO for RTC or PLL-synthesized system clock. Its digital system comprises 16 reconfigurable 8-bit blocks supporting composite peripherals like 32-bit timers, dual UARTs, and CRC/PRS modules.

Analog resources include 12 dedicated PSoC blocks enabling simultaneous high-precision signal chain functions - e.g., PGA + decimator + 14-bit ADC - with eight standard analog inputs routed to any GPIO and four additional analog inputs constrained to specific pins. All analog paths are rail-to-rail and share a common on-chip voltage reference.

FAQ

What development tools are required to program CY8C29466-24PVXI?

PSoC Designer™ (free Windows IDE) is the official development environment, supporting drag-and-drop peripheral configuration, automatic API generation, and ISSP-based programming. Required hardware includes MiniProg1 or MiniProg3 programmers. No JTAG adapter is needed - programming uses only VDD, VSS, SCLK, and SDATA pins.

Does CY8C29466-24PVXI support true 14-bit analog-to-digital conversion?

Yes - the device achieves effective 14-bit resolution using a sigma-delta decimator architecture within its analog blocks. This requires external RC filtering on analog inputs and proper grounding layout, but no external components are needed for basic operation. Measured ENOB is 13.2 bits typical at 100 SPS with internal reference.

Can the internal 24 MHz oscillator meet timing requirements for UART communication?

Yes - the ±5% oscillator tolerance is sufficient for UART operation up to 115.2 kbps at 3.3 V and 25 °C. For higher baud rates or wider temperature ranges, use the 32.768 kHz ECO with PLL to generate a crystal-referenced 24 MHz clock, achieving <0.1% error across –40 °C to +85 °C.

Is EEPROM emulation reliable for storing calibration data across product lifetime?

Yes - the device emulates up to 2 KB of EEPROM in flash using wear-leveling algorithms built into the PSoC Designer-generated bootloaders. Endurance is rated at 100,000 write cycles per logical address, with data retention exceeding 20 years at 85 °C - validated per Cypress AN2222 and Infineon reliability reports.
