Infineon Technologies CY8C24033-24PVXI

Overview

CY8C24033-24PVXI from Cypress Semiconductor is an 8-bit programmable system-on-chip (PSoC) featuring an M8C CPU core running at up to 24 MHz, 8 KB flash, 256 bytes SRAM, and configurable analog/digital blocks. It integrates a high-speed 8-bit SAR ADC (300 kSPS), four digital PSoC blocks, four analog PSoC blocks, and supports motor control, sensor interfacing, and embedded control in industrial and consumer systems.

For engineers reviewing the CY8C24033-24PVXI datasheet, CY8C24033-24PVXI pinout, CY8C24033-24PVXI application, or CY8C24033-24PVXI equivalent, key selection criteria include its 24 MHz M8C core speed, 8 KB Flash/256 B SRAM memory map, rail-to-rail analog block capability, 25 mA GPIO sink strength, and industrial temperature range (–40°C to +85°C).

Technical Context

The CY8C24033-24PVXI implements a Harvard-architecture M8C core with 4 MIPS throughput and integrated interrupt controller (11 vectors), enabling deterministic real-time execution. Its digital system comprises four 8-bit PSoC blocks that can be combined into 8–32-bit peripherals including PWMs, timers, UART, SPI, and CRC modules.

The analog system includes a dedicated 8-bit SAR ADC (monotonic, 300 kSPS) and four configurable analog blocks-two switched-capacitor (SC) and one continuous-time (CT)-supporting programmable gain amplifiers, filters, comparators, and dual 30 mA analog outputs.

FAQ

What is the maximum ADC sampling rate supported by CY8C24033-24PVXI?

The device features an 8-bit SAR ADC rated for up to 300 kSPS with guaranteed monotonicity. This performance is achieved using internal timing derived from the 24 MHz IMO or PLL-synchronized clocks, and is validated across the full industrial temperature range (–40°C to +85°C) per datasheet specification.

Does CY8C24033-24PVXI support in-circuit debugging?

Yes - it supports full-speed in-circuit emulation via the SWD interface using Cypress's MiniProg3 or KitProg programmers. Breakpoint capabilities include complex conditional breakpoints and 128 KB trace memory, enabling real-time instruction flow analysis without halting system operation.

Can the GPIO pins be configured for both analog input and digital output simultaneously?

No - each GPIO pin operates in a single mode per configuration cycle. However, runtime reconfiguration is supported: a pin may be set as analog input during ADC acquisition, then switched to strong-drive digital output for actuator control, under software control with minimal latency.

Is external crystal required for accurate UART communication?

No - the internal ±5% 24 MHz IMO is sufficient for UART operation up to 115.2 kbps with acceptable error margin. For higher baud rates (e.g., 921.6 kbps) or tighter tolerance requirements, the optional 32.768 kHz crystal with PLL is recommended to generate a precise 24 MHz system clock.
