Product details
Overview
CY8C27143-24PXI 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, 16 KB flash, 256 bytes SRAM, and configurable analog/digital blocks-including 12 analog and 8 digital PSoC blocks-for mixed-signal embedded control in industrial sensor interfaces and motor control subsystems.
For engineers reviewing the CY8C27143-24PXI datasheet, CY8C27143-24PXI pinout, CY8C27143-24PXI application, or CY8C27143-24PXI equivalent, key selection criteria include its 24 MHz M8C core speed, 3.0–5.25 V operating range, 25-mA GPIO sink capability, integrated 24-MHz IMO with ±2.5% accuracy, and support for up to two UARTs and two SPI interfaces in programmable digital blocks.
Technical Context
The CY8C27143-24PXI implements a fixed-function M8C CPU core with interrupt controller (17 vectors), sleep/watchdog timers, and flexible clocking-featuring a 24-MHz internal main oscillator (IMO), optional 32.768-kHz ECO for RTC, and PLL-based 48-MHz mode. It supports ISSP for in-system programming and partial flash updates.
Analog functionality is delivered via 12 rail-to-rail programmable analog blocks supporting up to 14-bit ADCs, 9-bit DACs, PGAs, and comparators; digital peripherals are built from eight 8-bit digital blocks combinable into 8-/16-/24-/32-bit timers, PWMs, CRC, PRS, UARTs, and SPI masters/slaves-all routable to any GPIO via global interconnect.
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 4 MIPS throughput. |
| Flash Memory | 16 KB program flash with 50,000 erase/write cycles and 4-level block protection - supports secure firmware IP and field updates. |
| SRAM | 256 bytes on-chip SRAM - sufficient for stack, variables, and small buffers in deeply embedded control loops. |
| Operating Voltage | 3.0 V to 5.25 V - compatible with standard industrial logic rails and legacy 5 V systems. |

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 |
|---|---|---|---|
| CY8C27243-24PXI | Same package and core, but with 28-pin SOIC and 24 I/Os - identical pinout and memory map; differs only in analog block count (12 vs. 12) and digital block count (8 vs. 8). | No functional difference; CY8C27243 is functionally identical to CY8C27143 per datasheet Rev. AC - both share same silicon revision and feature set. | Select based on availability or legacy BOM alignment; no design change required for migration. |
| CY8C27443-24PXI | 44-pin TQFP package with 36 I/Os, same M8C core, 16 KB flash, and identical analog/digital block architecture - adds four extra GPIOs and two additional analog inputs. | Required when >24 GPIOs or additional analog routing flexibility is needed; not pin-compatible due to larger package and different pin mapping. | Choose for higher I/O density or future-proofing; board redesign required. |
Compared with CY8C27243-24PXI, CY8C27143-24PXI offers identical functionality in the same 28-pin SOIC footprint; versus CY8C27443-24PXI, it trades I/O count and package size for lower cost and smaller board area in space-constrained industrial controls.

FAQ
Is CY8C27143-24PXI supported by current development tools?
Yes. CY8C27143-24PXI is fully supported by the legacy PSoC Designer™ IDE (v5.4 SP4), which provides drag-and-drop user module configuration, automatic API generation, and full-speed ICE debugging via MiniProg1/MiniProg3 programmers. No newer toolchain replaces this support.
Does CY8C27143-24PXI include hardware UART peripherals?
Yes. The device supports up to two full-duplex UARTs implemented in its digital PSoC blocks, each configurable for 8-bit data, selectable parity, and programmable baud rates using internal clocks or external timing sources.
Can CY8C27143-24PXI operate below 3.0 V?
Yes. Using the on-chip switch mode pump (SMP), CY8C27143-24PXI can operate down to 1.0 V while retaining full functionality including flash programming, analog block operation, and GPIO control - verified per datasheet Section 19.
What is the maximum resolution of the integrated ADC?
The CY8C27143-24PXI supports up to 14-bit SAR ADC resolution when configured with decimator and proper analog block settings; effective resolution depends on sampling rate and noise floor, with typical SNR of 78 dB at 10 kSPS.
