Product details
Overview
CY8C26233-24PVXI from Cypress Semiconductor is a programmable System-on-Chip (PSoC™) integrating an M8C 8-bit Harvard architecture CPU, 8K Flash, 256 bytes SRAM, 12 configurable analog blocks (including up to 11-bit Delta-Sigma ADC and 9-bit DAC), and 8 digital PSoC blocks (supporting PWM, UART, SPI, CRC). It operates at up to 24 MHz with 3.0–5.25 V supply and targets embedded control in industrial sensors and motor interface modules.
For engineers reviewing the CY8C26233-24PVXI datasheet, CY8C26233-24PVXI pinout, CY8C26233-24PVXI application, or CY8C26233-24PVXI equivalent, key selection considerations include its 28-pin SSOP package, ISSP™ in-system programming capability, analog block configurability via PSoC Designer GUI, and legacy support status as Not Recommended for New Designs per Cypress Rev. *C documentation.
Technical Context
This device implements a fully static CMOS PSoC architecture with dual-array programmability: analog blocks support Delta-Sigma and incremental ADCs, programmable gain amplifiers, and differential comparators; digital blocks deliver multipurpose timers, full-duplex UARTs, and SPI master/slave operation. All peripherals are routed through a flexible interconnect matrix.
Clocking combines internal 24/48 MHz oscillators (±2.5%), optional 32.768 kHz crystal input for PLL synchronization, and low-speed oscillator for watchdog/sleep modes. Memory includes 50,000-cycle Flash with EEPROM emulation (2,304 bytes) and partial update support.

Applications
| Industrial Sensor Interface | Motor Control Feedback Module |
|---|---|
Use Scenario: Condition monitoring of temperature, pressure, and current in factory automation nodes.

Use Value: Single-chip integration reduces BOM count and PCB area versus discrete MCU + ADC + op-amp solution. | Use Scenario: Closed-loop speed regulation in BLDC motor drives using hall-effect feedback. IC Role / Device Role / Timing Role: Incremental ADC digitizes hall sensor outputs; digital timers generate precise PWM with deadband for gate drivers. Use Value: On-chip analog front-end eliminates external signal conditioning, improving noise immunity and thermal stability. |
| Programmable Power Supply Monitor | Legacy Industrial Controller Upgrade |
Use Scenario: Real-time voltage/current supervision in DIN-rail mounted power supplies. IC Role / Device Role / Timing Role: Delta-Sigma ADC measures rail voltages; low-voltage detection circuit triggers fault response within 1 µs. Use Value: Internal voltage reference and programmable thresholds eliminate external supervisor ICs and trim components. | Use Scenario: Retrofitting aging PLC I/O modules with enhanced diagnostics and communication. IC Role / Device Role / Timing Role: SPI slave interface connects to host controller; SRAM buffers diagnostic logs; Flash stores configuration profiles. Use Value: ISSP™ enables field firmware updates to add new protocols or calibration algorithms without hardware change. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C27443-24PVXI | 16 KB Flash, 512 bytes SRAM, enhanced analog routing, silicon revision D vs. original C | Supports larger firmware images and more complex analog signal chains | Preferred for new designs requiring extended memory or improved analog performance |
| CY8C26443-24PVXI | 16 KB Flash, same 256 bytes SRAM, additional digital blocks (12 vs. 8), identical analog array | Better suited for designs needing multiple concurrent UART/SPI interfaces or advanced timer configurations | Select when digital peripheral count-not analog capability-is the limiting factor |
Compared with CY8C26233-24PVXI, CY8C27443 offers higher memory and updated silicon, while CY8C26443 adds digital resources without increasing analog capacity-making each suitable where their respective resource ceilings align with system requirements.

FAQ
Is CY8C26233-24PVXI still recommended for new designs?
No. Cypress explicitly labels this device "Not Recommended for New Designs" in Rev. *C documentation, directing users to CY8C27xxx series for enhanced Flash, SRAM, and analog routing. Legacy design support and obsolescence mitigation remain available through Aetrix Electronics' long-term supply program.
What development tools are required to program CY8C26233-24PVXI?
PSoC Designer IDE (v5.4 or earlier) is mandatory; it provides graphical peripheral configuration, code generation, and ISSP™ programming via MiniProg1 or compatible programmers. No third-party toolchains support the M8C core or PSoC 1 architecture.
Does CY8C26233-24PVXI support USB or CAN interfaces?
No. This device lacks native USB or CAN transceivers or protocol stacks. Communication is limited to UART, SPI, and I²C (via GPIO bit-banging only). External PHYs or bridge ICs are required for USB/CAN connectivity.
Can analog blocks be used simultaneously with digital blocks?
Yes. The PSoC 1 architecture allows concurrent operation: analog blocks process sensor signals while digital blocks execute PWM timing or UART transmission. Resource conflicts are resolved at compile time in PSoC Designer based on routing constraints and clock domain assignments.
