Infineon Technologies CY8C24633-24PVXIT

Overview

CY8C24633-24PVXIT from Cypress Semiconductor is a PSoC® 1 programmable system-on-chip integrating an M8C 8-bit Harvard-architecture CPU (24 MHz), 8 KB flash, 256 bytes SRAM, four digital PSoC blocks, four analog PSoC blocks, and an 8-bit SAR ADC (300 kSPS). It operates from 3.0–5.25 V across –40 °C to +85 °C and supports motor control, sensor interface, and embedded control applications with configurable analog/digital peripherals.

For engineers reviewing the CY8C24633-24PVXIT datasheet, CY8C24633-24PVXIT pinout, CY8C24633-24PVXIT application, or CY8C24633-24PVXIT equivalent, key selection criteria include its 24 MHz M8C core timing, rail-to-rail analog block configurability, 25 mA GPIO sink capability, and support for ISSP-based in-system programming - all critical for resource-constrained industrial and motor-control designs.

Technical Context

The CY8C24633-24PVXIT implements a fixed-function M8C core with 11-interrupt-vector controller, internal ±5% 24 MHz IMO (doublable to 48 MHz), and optional 32.768 kHz crystal + PLL for 24 MHz crystal-accurate clocking. Its digital system uses four 8-bit PSoC blocks combinable into 8–32-bit timers, PWMs, UART, SPI, and CRC modules, all routable to any GPIO via global digital interconnect.

The analog system integrates one dedicated 8-bit SAR ADC (300 kSPS, monotonic, motor-control optimized) plus four analog blocks - including one CT and two SC blocks per column - supporting programmable gain amplifiers (up to 93×), filters, comparators, and dual 30 mA analog outputs. Analog inputs are available on up to eight GPIO pins plus two restricted-routing inputs.

FAQ

Does CY8C24633-24PVXIT support in-circuit debugging?

Yes. It features full-speed in-circuit emulation via the SWD (Serial Wire Debug) interface, compatible with Cypress MiniProg3 programmers. Breakpoint structure supports complex conditional triggers, and 128 KB trace memory enables real-time instruction flow analysis during runtime without halting execution.

What is the maximum achievable ADC sampling rate with guaranteed monotonicity?

The integrated 8-bit SAR ADC achieves 300 kSPS with guaranteed monotonic response across the full operating temperature and voltage range. This specification is validated per datasheet Figure 12-1 and applies only when using the dedicated SAR8 block - not SC-block-derived ADCs.

Can all GPIO pins be used for both analog input and digital functions simultaneously?

No. While up to eight GPIO pins (P0[0–7], P1[0–3], P2[0,2,4,6]) support analog input routing, concurrent analog and digital use on the same pin requires careful timing coordination. Analog input paths must be disabled during digital read/write operations to prevent coupling-induced measurement error.

Is ISSP programming supported over standard UART or I²C interfaces?

No. In-System Serial Programming requires the dedicated SWD interface (pins SWDIO and SWCLK) and Cypress-specific protocol. UART and I²C are available for application-level communication only and cannot be repurposed for flash programming or debug access.
