Product details
Overview
CY8C24533-24PVXI from Infineon Technologies (formerly Cypress) is a programmable 8-bit Harvard-architecture PSoC® SoC integrating an M8C CPU core, four digital PSoC blocks, four analog PSoC blocks, 8 KB flash, 256 bytes SRAM, and configurable GPIO with 25-mA sink capability. It operates from 3.0 V to 5.25 V across –40 °C to +85 °C and features a high-speed 8-bit SAR ADC (300 kSPS), programmable gain amplifiers, and PWMs - used in motor control, sensor interface, and industrial embedded systems.
For engineers reviewing the CY8C24533-24PVXI datasheet, CY8C24533-24PVXI pinout, CY8C24533-24PVXI application, or CY8C24533-24PVXI equivalent, key selection factors include its 24 MHz M8C core speed, on-chip 24/48 MHz IMO oscillator ±5%, 8-bit SAR ADC monotonicity guarantee, flexible analog block routing, and ISSP-capable flash with 50,000 erase/write cycles.
Technical Context
The CY8C24533-24PVXI implements a fully configurable mixed-signal architecture where digital and analog resources are interconnected via global digital/analog busing. Its M8C core executes at up to 24 MHz with 8×8 multiply and 32-bit accumulate support, enabling real-time signal processing without external co-processors.
Digital peripherals include 8-/16-bit PWMs with dead-band, UART, SPI, I²C (up to 400 kHz), CRC/PRS modules, and timers built from combinable 8-bit digital blocks. Analog subsystems feature rail-to-rail opamp-based blocks supporting filters, comparators, DACs (6–9 bit), and a dedicated 8-bit SAR ADC optimized for motor control with monotonic response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| M8C Core Speed | 24 MHz maximum - enables real-time control loops with sub-42 ns instruction cycle time. |
| Flash / SRAM | 8 KB flash (50,000 erase/write cycles) + 256 bytes SRAM - supports field-upgradable firmware and small data buffers. |
| SAR ADC | 8-bit, 300 kSPS, monotonic - suitable for closed-loop motor phase current sampling without calibration overhead. |
| Analog Blocks | Four configurable analog blocks (1 CT + 3 SC), including two 30-mA analog outputs - enable custom signal conditioning chains without external opamps. |
| Digital Blocks | Four 8-bit digital blocks, combinable into 8-/16-/24-/32-bit peripherals - allows hardware-accelerated PWM, UART, and CRC generation routed to any GPIO. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Primary 3.0–5.25 V supply for core, analog, and digital systems; requires local 0.1 µF decoupling. |

Key Features
| Feature | Design Value |
|---|---|
| In-system serial programming (ISSP) | Enables firmware updates over two-wire interface without removing device from PCB. |
| 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 terminators. |
| Global digital/analog interconnect | Allows any digital block output or analog block input to be routed to any GPIO - removes fixed-peripheral pin constraints. |
| On-chip voltage reference | 1.3 V precision bandgap reference - provides stable ADC/DAC reference independent of VDD variation. |
| Low-voltage detection (LVD) | User-configurable threshold (2.2–4.8 V) with interrupt output - enables graceful shutdown before brownout corruption. |
Applications
| Motor Control Interface | Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Real-time acquisition and modulation of three-phase motor currents and position feedback signals. IC Role / Device Role / Timing Role: Central mixed-signal controller executing FOC algorithms, generating synchronized PWMs with dead-band, and digitizing analog current sense outputs. Use Value: Integrated 8-bit SAR ADC (300 kSPS, monotonic) and programmable analog blocks eliminate external ADCs and opamp stages, reducing BOM count by ≥4 components. |
Use Scenario: Condition and digitize outputs from resistive temperature detectors (RTDs), thermistors, and bridge-based pressure sensors. IC Role / Device Role / Timing Role: Programmable gain amplifier + filter + 8-bit ADC chain with on-chip 1.3 V reference - performs ratiometric measurement without external references. Use Value: Configurable analog blocks support 2-pole low-pass filtering and PGA gain up to 48×, enabling direct connection to microvolt-level sensor outputs. |
| Industrial HMI Keypad | Smart Actuator Control |
|
Use Scenario: Scan matrix keypad, debounce keys, drive LED indicators, and communicate status via I²C to host MCU. IC Role / Device Role / Timing Role: Self-contained peripheral manager using digital blocks for timer-based scanning, GPIO interrupts for key press detection, and I²C slave interface. Use Value: 25-mA sink per GPIO drives LEDs directly; ISSP allows firmware updates in-field without rework - reduces service downtime. |
Use Scenario: Closed-loop control of solenoid valves and stepper drivers in fluid handling systems with fault monitoring. IC Role / Device Role / Timing Role: Combines analog comparator for overcurrent detection, PWM for valve timing, watchdog timer for safety timeout, and LVD for power-fail response. Use Value: Integrated supervisory circuit (POR/LVD/WDT) and configurable analog comparators with 16 thresholds replace discrete supervisor ICs and comparator networks. |
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 |
|---|---|---|---|
| CY8C24423A-24PVXI | 4 KB flash, no SAR ADC, same M8C core and package - lacks motor-control-optimized ADC and analog column 0. | Suitable for pure digital control tasks without analog sensing; not viable for current-loop feedback. | Select when cost sensitivity outweighs need for integrated ADC and analog signal chain. |
| CY8C27443-24PVXI | 16 KB flash, 1 KB SRAM, 12 analog blocks, 12 digital blocks - larger resource set but 28-pin SOIC footprint unchanged. | Supports more complex multi-channel sensor fusion or dual-motor control; higher code/data headroom. | Choose when firmware complexity exceeds 8 KB or analog channel count > 8 required. |
Compared with CY8C24423A-24PVXI, this part adds monotonic 8-bit SAR ADC and analog column 0 for motor control; versus CY8C27443-24PVXI, it trades flash/SRAM size and analog block count for lower unit cost and simpler toolchain configuration.

FAQ
Does CY8C24533-24PVXI support in-application programming (IAP) during runtime?
No - it supports only in-system serial programming (ISSP) via dedicated programming pins (P1[6]/P1[7]) with external programmer. Runtime flash modification is not supported due to lack of dual-bank flash architecture and absence of bootloader API in M8C instruction set.
Can the 8-bit SAR ADC perform simultaneous sampling across multiple channels?
No - the SAR ADC is single-channel with multiplexed analog input routing. It sequentially samples enabled channels at up to 300 kSPS total throughput; true simultaneous sampling requires external parallel ADCs or higher-tier PSoC devices with multiple ADC cores.
What is the maximum operating frequency of the internal main oscillator (IMO) when used with PLL?
The IMO is factory-trimmed to 24 MHz ±5% and can be doubled to 48 MHz using the on-chip PLL. This 48 MHz clock is valid only for digital system use; analog blocks and ADC operate from divided clocks derived from IMO or ECO sources.
Is the 1.3 V internal voltage reference available as an external pin output?
No - the 1.3 V bandgap reference is internal-only and feeds ADC, DAC, and comparator reference inputs. It cannot be routed to GPIO pins; external reference must be supplied via RefHi/RefLo pins if absolute accuracy beyond ±1% is required.
