The 4 KB SRAM is sufficient for a couple of UART buffers and a modest state machine. If your firmware image is pushing past 12 KB, check whether the 16 KB ceiling leaves room for a field-update staging area. The 4K x 8 SRAM is organized as a single block, so heap fragmentation is something to budget for early. ## Programmable analog: 8-channel 12-bit SAR ADC and dual IDACs The 8-channel 12-bit SAR ADC runs at up to 1 Msps (typical) and can be sequenced autonomously, freeing the CPU for other tasks. Two current-mode IDACs are available for sensor excitation or closed-loop control. This analog front-end is what distinguishes the PSOC 4 from a plain Cortex-M0 — it replaces a separate ADC or DAC on the BOM for many industrial and consumer sensing applications. For production programs that need multi-year supply assurance, the CY8C4124PVI-432 is a stable choice. The PSOC 4 family has broad adoption, so allocation risk is lower than on niche or sole-sourced MCUs. ## 28-pin SSOP — footprint and reflow considerations It is compatible with conventional reflow profiles (MSL 3 per IPC/JEDEC). No exposed pad — thermal dissipation is through the leads, so keep the ambient below 85°C for continuous operation near the maximum current draw. The 24 I/O lines are 5 V tolerant on most pins, simplifying level translation when interfacing to 5 V logic or sensors.","metaTitle":"CY8C4124PVI-432 Infineon PSOC 4 MCU, 24 MHz ARM Cortex-M0","metaDescription":"Infineon CY8C4124PVI-432 PSOC 4 MCU: 24 MHz ARM Cortex-M0, 16 KB Flash, 4 KB SRAM, 24 I/O, 1.71 V to 5.5 V, -40°C to 85°C, 28-SSOP.","metaKeywords":null},"attributes":{"series":"PSOC® 4 CY8C4100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"24MHz","Series":"PSOC® 4 CY8C4100","Package":"Tube","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, LVD, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, Microwire, SmartCard, SPI, SSP, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"24","Core Processor":"ARM® Cortex®-M0","Package / Case":"28-SSOP (0.209\\\", 5.30mm Width)","Data Converters":"A/D 8x12b SAR; D/A 2xIDAC","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"28-SSOP","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.92000","currency":"USD"},{"qty":10,"price":"$2.62000","currency":"USD"},{"qty":25,"price":"$2.47720","currency":"USD"},{"qty":100,"price":"$2.14680","currency":"USD"},{"qty":250,"price":"$2.03668","currency":"USD"},{"qty":500,"price":"$1.82750","currency":"USD"},{"qty":1000,"price":"$1.54126","currency":"USD"},{"qty":2500,"price":"$1.46420","currency":"USD"},{"qty":5000,"price":"$1.40915","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2b4f8dee9139494317cb4172e8a50611.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to CY8C4124PVI-432?","answer":"Within the same PSOC 4 family, the CY8C4245LQI-483 offers a 48 MHz core, more I/O (34), and additional peripherals like CapSense and LCD drive, but comes in a QFN package.
