Product details
Overview
CY8C26233-24PVIT from Cypress Semiconductor is a programmable System-on-Chip (PSoC™) integrating an M8C 8-bit Harvard architecture CPU, 8 KB Flash program memory, 256 bytes SRAM, 12 configurable analog PSoC blocks (including up to 11-bit Delta-Sigma ADC and 9-bit DAC), and 8 digital PSoC blocks (supporting PWM, UART, SPI, and CRC). It operates at up to 24 MHz with supply voltage from 3.0 V to 5.25 V and targets embedded sensor interface and mixed-signal control applications.
For engineers reviewing the CY8C26233-24PVIT datasheet, CY8C26233-24PVIT pinout, CY8C26233-24PVIT application, or CY8C26233-24PVIT equivalent, key selection criteria include on-chip analog configurability, ISSP™ in-system programming support, 24 MHz CPU speed, 8 KB Flash endurance (50,000 erase/write cycles), and operation across -40 °C to +85 °C industrial temperature range.
Technical Context
The CY8C26233-24PVIT implements a fully static CMOS design with dual-clock domains: a high-speed system clock (up to 24 MHz derived from internal 24/48 MHz oscillator or external crystal) and a low-speed domain for watchdog/sleep timers. Its analog subsystem uses switch-capacitor and continuous-time architectures, enabling user-defined signal chains such as programmable-gain amplifiers, low-pass filters, and differential comparators without external components.
Digital functionality is implemented via eight reconfigurable digital PSoC blocks supporting timer-based functions (PWM with deadband, RTC), serial interfaces (full-duplex UART, SPI master/slave), and CRC generation. All peripherals are routed through a flexible interconnect matrix and configured via PSoC Designer software-generated register maps-not fixed hardware assignments.

The PSoC™ 2 family-including CY8C26233-was designed to replace discrete analog/digital components with a single configurable chip for cost-sensitive, medium-complexity embedded control applications where rapid prototyping and analog flexibility are essential.
FAQ
Is CY8C26233-24PVIT still recommended for new designs?
No. Cypress explicitly marks CY8C26233-24PVIT as "Not Recommended for New Designs" in its official datasheet (Rev. *C, May 2005), directing users to migrate to the CY8C27xxx series. While fully functional and supported for legacy production, new projects should use CY8C27443 or later PSoC 2 variants for extended lifecycle, improved specs, and ongoing toolchain updates.
What programming tools are required for CY8C26233-24PVIT?
The CY8C26233-24PVIT requires Cypress's discontinued PSoC Designer IDE (v5.4 or earlier) and MiniProg1 or MiniProg3 programmers. No modern IDE supports this device natively; legacy installations must be preserved. Code is compiled to M8C assembly, and configuration is stored in Flash via ISSP™ using SWD pins P1[0] and P1[1].
Does CY8C26233-24PVIT support USB or CAN interfaces?
No. The CY8C26233-24PVIT lacks native USB or CAN transceivers or protocol engines. It supports UART, SPI, and I²C for serial communication. USB or CAN connectivity requires external PHY chips and firmware-implemented protocol stacks-neither is integrated nor optimized in the PSoC 2 architecture.
Can CY8C26233-24PVIT operate below 3.0 V?
Yes-down to 1.0 V-using its on-chip switch-mode voltage pump (SMVP), which boosts internal core voltage while allowing I/O to remain at reduced supply. This mode supports ultra-low-power sleep states but disables certain analog blocks and reduces maximum CPU speed; full functionality (24 MHz, all peripherals) requires ≥3.0 V.
