Product details
Overview
CY8C27443-24PVIT from Cypress Semiconductor is a programmable mixed-signal array (PSoC™) integrating an M8C 8-bit Harvard architecture CPU, 16 KB Flash, 256 bytes SRAM, 8 digital PSoC blocks, and 12 analog PSoC blocks in a 28-pin SSOP package. It operates at up to 24 MHz, supports 3.0–5.25 V supply (or 1.0 V with on-chip switch-mode pump), and delivers rail-to-rail analog performance with configurable GPIO, ADCs (up to 14-bit), DACs (up to 9-bit), timers, PWMs, UARTs, and I²C for embedded control in industrial sensor interfaces.
For engineers reviewing the CY8C27443-24PVIT datasheet, CY8C27443-24PVIT pinout, CY8C27443-24PVIT application, or CY8C27443-24PVIT equivalent, key selection criteria include its programmable analog/digital block count, 24 MHz M8C core speed, 28-pin SSOP footprint, 12-channel analog input capability, and support for in-system serial programming (ISSP™) and EEPROM emulation in Flash.
Technical Context
The CY8C27443-24PVIT implements a fully configurable mixed-signal architecture with two rows of four digital blocks (total 8) and four columns of three analog blocks (total 12), interconnected via global digital and analog buses. Its M8C core executes at 24 MHz with 8×8 multiply/32-bit accumulate capability and 17-interrupt-vector controller.
Analog resources include programmable gain amplifiers (up to 48×), Delta-Sigma/SAR/Incremental ADCs (6–14 bit), comparators with 16 thresholds, and 30 mA analog output drivers. Digital resources support up to two full-duplex UARTs, multiple SPI masters/slaves, CRC/PRS modules, and 8–32-bit timers/counters/PWMs-all routable to any GPIO.

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 |
|---|---|---|---|

| CY8C29466-24PVXI | Higher resource count: 16 digital blocks, 12 analog blocks, 64 I/O, 32 KB Flash, but 100-pin TQFP package | Supports complex multi-peripheral systems (e.g., dual CAN + USB + motor control) unsuitable for 28-pin footprint | Choose only if design requires >8 digital blocks or >44 GPIO - not a drop-in replacement |
Compared with CY8C27443-24PVXI, the -24PVIT offers lower cost and standard temp range for commercial applications; versus CY8C29466-24PVXI, it trades scalability for compactness and power efficiency - ideal for space-constrained, single-function embedded nodes.

FAQ
Does CY8C27443-24PVIT support in-system programming without external hardware?
Yes. It features integrated ISSP™ (In-System Serial Programming) using only SWD and RESET pins, enabling firmware updates via UART or USB-to-UART adapter without dedicated programmers. The PSoC Designer IDE generates ready-to-deploy .hex files compatible with Cypress-provided bootloader code.
What is the maximum resolution achievable for ADC conversion on this device?
The CY8C27443-24PVIT supports up to 14-bit resolution using its Delta-Sigma ADC configuration, with effective number of bits (ENOB) of 12.5 bits typical at 100 SPS. Resolution is selectable per channel (6–14 bit), and oversampling can improve SNR at lower throughput rates.
Can all GPIO pins be used for analog input simultaneously?
No. While up to 12 analog inputs are supported, they share multiplexed paths through Port 0 and Port 2 pins. Only 8 pins (P0[0]–P0[7]) are routed to the analog input mux; P2[0], P2[1], P2[2], and P2[4] provide additional analog-capable inputs, but concurrent use depends on selected analog block routing and reference configuration.
Is there hardware support for LIN bus communication?
No dedicated LIN transceiver is integrated, but the device supports LIN 2.1 protocol in software using its UART with programmable break detection and timing. The 24 MHz clock and flexible timer blocks allow precise 19.2 kbps baud rate generation and sync field timing - validated in Cypress Application Note AN2112.
