Product details
Overview
CY8C26233-24PVI from Cypress Semiconductor is a programmable System-on-Chip (PSoC™) integrating an M8C 8-bit Harvard-architecture CPU, 8 KB Flash, 256 B SRAM, 12 configurable analog blocks (including ΔΣ ADC, DAC, PGA, filters), and 8 digital PSoC blocks (PWM, UART, SPI, timers). It operates at up to 24 MHz, supports 3.0–5.25 V supply, and targets embedded control with mixed-signal flexibility in industrial sensors and motor interface modules.
For engineers reviewing the CY8C26233-24PVI datasheet, CY8C26233-24PVI pinout, CY8C26233-24PVI application, or CY8C26233-24PVI equivalent, key selection criteria include on-chip analog configurability, ISSP™ in-system programming, 24 MHz CPU speed, 8 KB Flash endurance (50,000 cycles), and support for precision sensor signal conditioning with programmable gain amplifiers and delta-sigma conversion.
Technical Context
The device implements a fully static CMOS architecture with dual-clock domains: a high-speed system clock (up to 24 MHz from internal oscillator ±2.5%) and independent analog block clocks (programmable dividers from 24/48 MHz source or external 32.768 kHz crystal). Analog resources are organized into 12 user-configurable blocks supporting simultaneous operation of multiple functions-e.g., one block as a 11-bit ΔΣ ADC while another serves as a 9-bit DAC with programmable output drive up to 40 mA.
Digital functionality is distributed across eight reconfigurable PSoC blocks, each capable of implementing UART, SPI, PWM with deadband, CRC, or timer-based real-time clock-all synchronized via global inputs/outputs and interrupt routing through a centralized vector table. Memory mapping includes separate Flash (4–16 KB variants) and SRAM (256 B), with EEPROM emulation (2,304 B) enabled via firmware-managed Flash sectors.

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 |
|---|---|---|---|
| CY8C26443-24PVX | 16 KB Flash, 4 KB SRAM, 24-pin SSOP package; same PSoC 1 architecture and peripheral set | Higher memory capacity supports larger firmware images and more complex state machines | Select when application requires >8 KB code space or needs smaller footprint than PDIP |
| CY8C27443-24PVX | PSoC 3 architecture (8051 core), 32 KB Flash, 2 KB SRAM, enhanced analog performance (12-bit SAR ADC, 12-bit DAC) | Superior analog precision and throughput; not pin-compatible; requires PSoC Creator toolchain | Choose for new designs needing higher-resolution ADC/DAC or faster CPU; migration path from CY8C26233 |
Compared with CY8C26443-24PVX, CY8C26233-24PVI offers identical peripheral configurability in a legacy PDIP package but with less memory; versus CY8C27443-24PVX, it trades modern 8051 performance and precision analog for proven PSoC 1 toolchain compatibility and lower cost in mature industrial designs.

FAQ
Is CY8C26233-24PVI still recommended for new designs?
No. Cypress explicitly marks this device as "Not Recommended for New Designs" in its official documentation, advising migration to the CY8C27xxx series (PSoC 3) or later generations. However, it remains supported for legacy production and repair, with full datasheet, toolchain (PSoC Designer), and programming documentation available.
What development tools are required to program CY8C26233-24PVI?
The official toolchain is PSoC Designer v5.4 (last supported version), which provides graphical peripheral configuration, automatic code generation, and ISSP™ programming via MiniProg1 or compatible programmers. No third-party IDEs or compilers are officially supported; GCC or Keil toolchains are incompatible with the M8C core.
Does CY8C26233-24PVI support hardware debugging during runtime?
Yes-it features a two-wire Serial Wire Debug (SWD) interface compliant with ISSP™ specification, enabling breakpoints, register inspection, and real-time variable monitoring via MiniProg1 or CY3210-DEV-PSoC kits. Full in-circuit emulation is supported, but JTAG is not implemented on this device.
Can analog blocks operate simultaneously with different clock sources?
Yes. Each analog PSoC block has independent clock select registers allowing assignment of distinct clock dividers sourced from the internal 24/48 MHz oscillator or external 32.768 kHz crystal. This enables concurrent operation of a high-speed ΔΣ ADC and low-power comparator bus without timing conflict.
