Product details
Overview
CY8C24533-24PVXIT from Infineon Technologies (formerly Cypress) is a programmable PSoC® 1 System-on-Chip integrating an M8C 8-bit Harvard-architecture CPU, four digital PSoC blocks, four analog PSoC blocks, and an 8-bit SAR ADC optimized for motor control. It operates at up to 24 MHz, supports 3.0–5.25 V supply, and delivers 300 kSPS ADC conversion with monotonicity guarantee in industrial temperature range (–40 °C to +85 °C), used in embedded motor control and sensor interface systems.
For engineers reviewing the CY8C24533-24PVXIT datasheet, CY8C24533-24PVXIT pinout, CY8C24533-24PVXIT application, or CY8C24533-24PVXIT equivalent, key selection criteria include its configurable analog/digital blocks, 8-KB flash with EEPROM emulation, 256-byte SRAM, flexible GPIO drive modes (25 mA sink, 30 mA analog output), and integrated I²C, UART, and PWM peripherals for rapid system integration.
Technical Context
The CY8C24533-24PVXIT implements a unified programmable architecture where digital and analog resources are interconnected via global digital/analog buses, enabling custom peripheral synthesis without external components. Its M8C core executes at 24 MHz with 4-MIPS throughput and supports 11 interrupt vectors for deterministic real-time response.
Analog functionality centers on an 8-bit SAR ADC (300 kSPS, monotonic), two 6–9-bit DACs, programmable gain amplifiers (up to 93×), and filter/comparator blocks-all configurable through PSoC Designer. Digital resources include 8–32-bit timers, 8-/16-bit PWMs with dead-band, CRC/PRS modules, and full-duplex UART routed to any GPIO.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C24423A-24PVXI | 4 KB flash, no SAR ADC, same M8C core and PSoC block count - lacks motor-optimized ADC and analog output drivers. | Suitable for digital-only control tasks (e.g., simple timer/PWM sequencers) without analog sensing or closed-loop feedback. | Select when analog signal acquisition is unnecessary and cost reduction is prioritized over ADC integration. |
| CY8C27443-24PVXI | 16 KB flash, 1 KB SRAM, 12 analog blocks, no SAR ADC - higher memory and analog resource count but no integrated ADC. | Better suited for complex analog signal processing (e.g., multi-channel filtering, multi-stage amplification) without high-speed sampling requirements. | Choose when scaling analog path complexity outweighs need for on-chip ADC - requires external ADC for sampling-critical functions. |
Compared with CY8C24533-24PVXIT, CY8C24423A-24PVXI trades ADC capability for lower cost and density, while CY8C27443-24PVXI expands analog configurability at the expense of ADC integration - making CY8C24533-24PVXIT optimal for cost-sensitive motor control where 300 kSPS sampling and analog outputs are essential.

FAQ
Does CY8C24533-24PVXIT support in-system programming without a dedicated programmer?
Yes. It supports In-System Serial Programming (ISSP) via dedicated pins (e.g., SCLK, SDAT, XRES), enabling firmware updates using low-cost external programmers or host microcontrollers. No JTAG adapter is required, and partial flash updates are supported to minimize downtime during field maintenance.
What is the maximum resolution achievable with the SAR ADC when oversampling is applied?
The SAR ADC is fixed at 8-bit resolution per conversion. Oversampling is not natively supported in hardware; however, firmware-based averaging of multiple samples can improve effective resolution to ~10 bits at reduced effective sampling rate (e.g., 75 kSPS for 2× average). No hardware decimation or delta-sigma modulation is integrated.
Can the 30-mA analog outputs drive standard 4–20 mA current loops directly?
No. The 30-mA analog outputs are voltage-mode drivers (not current-sourcing) and lack built-in current-loop compliance voltage or sense feedback. They can drive low-impedance loads (e.g., op-amp inputs, 1-kΩ potentiometers) but require external circuitry (e.g., op-amp + transistor) to implement a true 4–20 mA transmitter.
Is the internal 1.3-V voltage reference available for external use?
No. The 1.3-V internal reference is dedicated to internal ADC/DAC operation and is not routed to any package pin. External precision references must be supplied separately if higher accuracy or external analog circuit biasing is required.
