It integrates 16 KB of Flash program memory, 24 general-purpose I/O pins, and on-chip data converters: a 4-channel 14-bit ADC and a 4-channel 9-bit DAC. ## Mixed-signal integration — what the 14-bit ADC and 9-bit DAC mean for the BOM The 4-channel, 14-bit successive-approximation ADC resolves analog inputs from potentiometers, thermistors, or current-sense resistors without an external converter. The 4-channel 9-bit DAC generates analog setpoints or reference voltages for downstream circuitry. For a design that needs a few analog inputs and outputs alongside digital control, this integration collapses the signal chain into one IC — saving the cost and footprint of an external ADC/DAC pair and the associated level-shifting. ## 24 I/O and serial interfaces — fitting the peripheral map With 24 I/O pins, the CY8C27443-24PVXI can handle a keypad matrix, a few LED indicators, and a serial link to a host controller. If your design needs more than 24 I/O, the pin-compatible CY8C29466-24PVXI (same 28-SSOP package) offers the same core and peripherals but with 12 ADC channels — though I/O count remains 24; for 40 I/O, step up to the CY8C29566-24AXIT in a 48-pin QFP. ## Package and footprint — 28-pin SSOP layout notes The 28-pin SSOP (shrink small-outline package) has a 0.65 mm pitch and a body width around 5.3 mm. It is a surface-mount package requiring standard reflow soldering. No exposed thermal pad — junction-to-ambient thermal resistance is handled through the leads and PCB copper.","metaTitle":"CY8C27443-24PVXI PSoC 1 MCU, 8-bit M8C 24 MHz, 16 KB Flash","metaDescription":"Infineon CY8C27443-24PVXI PSoC 1 8-bit MCU with M8C core at 24 MHz, 16 KB Flash, 4x14b ADC, 4x9b DAC, 24 I/O, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"series":"PSOC®1 CY8C27xxx","has_mpn":"CY8C27443","cpu_core":"M8C","frame_size":"8-Bit","fuse_speed":"24 MHz","connectivity":"I²C, SPI, UART/USART","package_type":"Tube","Number Of I/O":"24","mounting_type":"Surface Mount","product_status":"Active","Data Converters":"A/D 4x14b; D/A 4x9b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","peripheral_types":"POR, PWM, WDT","supply_voltage_v":"3.0","Program Memory Type":"FLASH","Operating Temperature High":"-40°C to 85°C (TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.72","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d402c25d314e801e736bd9567f91c494.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY8C27443-24PVXI/alternatives.json"},"ai":{"faq":[{"question":"How many I/O pins does CY8C27443-24PVXI have?","answer":"The CY8C27443-24PVXI provides 24 general-purpose I/O pins."},{"question":"Can CY8C27443-24PVXI be programmed with PSoC Creator?","answer":"Yes — PSoC Creator supports the PSoC 1 family including the CY8C27xxx series.
