Product details
Overview
CY8C24633-24PVXI from Cypress Semiconductor is a PSoC® 1 programmable system-on-chip featuring an M8C 8-bit Harvard-architecture CPU running at up to 24 MHz, 8 KB flash, 256 bytes SRAM, and integrated analog/digital PSoC blocks for mixed-signal embedded control. It supports industrial temperature range (–40 °C to +85 °C), operates from 3.0–5.25 V, and includes a high-speed 8-bit SAR ADC (300 kSPS) optimized for motor control.
For engineers reviewing the CY8C24633-24PVXI datasheet, CY8C24633-24PVXI pinout, CY8C24633-24PVXI application, or CY8C24633-24PVXI equivalent, key selection criteria include configurable analog blocks (4 CT/SC), digital block flexibility (timers, PWM, UART, SPI), GPIO drive modes (25 mA sink, 30 mA analog output), and ISSP-based in-system programming capability.
Technical Context
The device implements a fixed-function M8C core with 11-interrupt-vector controller, sleep/WDT timers, and dual-oscillator clocking (±5% 24 MHz IMO + optional 32.768 kHz ECO with PLL for crystal-accurate 24 MHz). Memory architecture separates 8 KB flash (50k erase/write cycles, 64-byte protection blocks) from 256-byte SRAM and emulated EEPROM.
Analog resources center on a dedicated 8-bit SAR ADC (monotonic, 300 kSPS) and four programmable analog blocks-three switched-capacitor (SC) and one continuous-time (CT)-supporting filters, PGAs (up to 93× gain), comparators (16 thresholds), and dual 6–9-bit DACs. Digital blocks are arranged in 4×1 array, connectable via global interconnect to any GPIO.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | M8C 8-bit Harvard architecture, 24 MHz max operation - enables deterministic real-time control with low latency interrupt response |
| Flash Memory | 8 KB with 50,000 erase/write cycles and 64-byte protection blocks - supports secure firmware updates and IP protection |
| SRAM | 256 bytes - sufficient for stack, variables, and small buffers in resource-constrained embedded control |
| SAR ADC | 8-bit, 300 kSPS, monotonic - meets timing-critical sampling needs in motor position/speed feedback loops |
| Analog Blocks | 4 total (1 CT + 3 SC), including SAR8 ADC block - enables concurrent signal conditioning, filtering, and comparison without external components |
| Digital Blocks | 4 × 8-bit blocks, combinable into 8–32-bit peripherals - allows custom PWM (with dead-band), UART, CRC, and PRS logic per application |

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 | Same M8C core, 4 KB flash, 256 bytes SRAM, identical 28-pin SOIC package and pinout | Limited analog block count (2 vs. 4); no SAR8 ADC block - unsuitable for motor control requiring fast sampling | Select when cost-sensitive designs require only basic GPIO, PWM, and simple analog functions without high-speed ADC |
| CY8C27443-24PVXI | Enhanced PSoC 1 family: 16 KB flash, 512 bytes SRAM, same 28-pin SOIC, adds USB interface and higher analog block density | Includes USB 1.1 transceiver - adds host/device connectivity but increases code size and power consumption | Choose when firmware update over USB or human-interface device (HID) functionality is required alongside mixed-signal control |
Compared with CY8C24423A-24PVXI, the CY8C24633-24PVXI delivers double flash capacity and full analog subsystem capability essential for closed-loop control; versus CY8C27443-24PVXI, it offers lower cost and power while retaining core motor/sensor processing features without USB overhead.

FAQ
What development tools are required to program the CY8C24633-24PVXI?
PSoC Designer™ (free Windows IDE) is the official toolchain, providing drag-and-drop user module configuration, automatic API generation, and full-speed emulation. Programming requires MiniProg1 or MiniProg3 via ISSP interface; no external debugger is needed for basic flash programming or debugging.
Does the CY8C24633-24PVXI support true hardware UART with FIFO or flow control?
No - it implements a single full-duplex UART with software-configurable parity and stop bits, but lacks hardware FIFO, RTS/CTS flow control, or automatic baud rate detection. Baud rates up to 115.2 kbps are achievable at 24 MHz with acceptable error margin (<±2%) using integer dividers.
Can the SAR8 ADC sample multiple channels simultaneously?
No - the 8-bit SAR ADC is single-channel with multiplexed inputs. It supports sequential sampling of up to eight analog sources (P0[0–7], P2[0,2,4,6]) via internal mux, but not true simultaneous sampling. Conversion time is fixed at ~3.3 µs per sample at 300 kSPS.
Is the 30 mA analog output capable of driving external loads directly?
Yes - two GPIO pins (P0[6], P0[7]) are designated as high-current analog outputs with 30 mA drive capability and rail-to-rail swing. They can directly drive opto-triacs, small solenoids, or LED strings without external buffer transistors, provided load voltage remains within VDD–0.5 V to VSS+0.5 V.
