It packs 4 KB of Flash program memory and 256 x 8 bytes of RAM into an 8-SOIC package, with 6 general-purpose I/O lines accessible through the surface-mount footprint. The distinguishing feature of this part is its integrated mixed-signal block: a 4-channel 14-bit ADC and a 2-channel 9-bit DAC, letting a single chip handle analog front-end conditioning and digital control without an external converter. Typical applications include sensor interface modules, handheld instruments, and low-power control nodes where board space is tight and the design needs one-chip analog-to-digital conversion. ## 24 MHz M8C core — throughput for serial-bus applications The 24 MHz clock rate on the M8C core handles I²C, SPI, and UART/USART traffic while servicing on-chip ADC conversions. The internal oscillator eliminates an external crystal. ## 4 KB Flash, no field updates possible The program memory is 4 KB of Flash, factory-programmable and field-reprogrammable through the chip's serial interface. That is a small code space — enough for a bootloader plus a few sensor-compensation routines, but not enough for a full protocol stack with a GUI menu. The 256 x 8 RAM is similarly tight; data logging beyond a few dozen samples will need external serial EEPROM or a larger PSoC 1 variant. ## Industrial temperature grade, 2.4 V to 5.25 V supply Rated for -40°C to 85°C ambient. Supply range from 2.4 V to 5.25 V. ## Active lifecycle — no LTB clock The CY8C24123A-24SXIT carries an Active product status. Infineon has not issued an end-of-life notice or a last-time-buy window for this order code. That means a BOM line using this part is not under a forced redesign timeline. For new-design qualification, the same mixed-signal capability is also available in the CY8C29466-24PVXI (24 I/O, 12x14b ADC, 4x9b DAC in a different package) if the 8-SOIC I/O count is too tight. ## Sourcing this part to your BOM This order code is sourced through independent distribution channels — confirmed available on request. Pricing and current stock levels are verified at quote time against the multi-source supply base. Submit an RFQ with your target quantity and required delivery window; the quote will reflect the best available channel position for this active PSoC 1 MCU.","metaTitle":"CY8C24123A-24SXIT PSoC 1 MCU, 8-Bit M8C, 24 MHz, 4KB Flash","metaDescription":"Infineon CY8C24123A-24SXIT 8-bit PSoC 1 MCU with M8C core at 24 MHz, 4KB Flash, 256x8 RAM, 4x14b ADC, 2x9b DAC, -40 to 85°C.

The toolchain handles the M8C core, the configurable analog and digital blocks, and the Flash programming through a MiniProg3 or compatible programmer. No external oscillator is needed because the part has an internal oscillator."},{"question":"What is the replacement for CY8C24123A-24SXIT if I need more I/O or memory?","answer":"Within the same PSoC 1 architecture at the same 24 MHz clock, the CY8C29566-24AXIT offers 40 I/O, 12x14b ADC channels, and 4x9b DAC channels in a larger package. The CY8C29466-24PVXI splits the difference with 24 I/O and the same 12x14b ADC / 4x9b DAC configuration. Both run the M8C core and share the same peripheral set (POR, PWM, WDT) and I²C/SPI/UART connectivity."},{"question":"What does the 24 MHz speed rating mean for this part?","answer":"The 24 MHz is the M8C core clock maximum. At this speed the CPU can execute one instruction per clock cycle for most operations, giving a throughput of roughly 24 MIPS. This is sufficient for polling a 14-bit ADC at sample rates up to several ksps while managing an I²C or SPI bus at 400 kHz or 1 MHz respectively. It is not intended for high-speed control loops or video processing — the PSoC 6 series (CY8C6137BZI-F54 with a 150 MHz Cortex-M4) would be the appropriate choice for those workloads."},{"question":"Is CY8C24123A-24SXIT RoHS compliant?","answer":"Yes, it is ROHS3 Compliant, meeting the current EU RoHS directive including the four phthalates. No conflict with standard compliance declarations for shipping into Europe or North America."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C24123A-24SXIT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C24123A-24SXIT when reusing this data.
