CY8C24123-24PI - 24MHz 8-Bit 4KB Flash MCU | Infineon
MPN： CY8C24123-24PI ✓ 啟用中CY8C24123-24PI 概覽
A microcontroller is a programmable semiconductor that executes firmware, reads inputs, controls outputs, and interfaces with sensors, actuators, communications circuits, and human-interface equipment. The PSoC 1 family integrates configurable analog and digital blocks with an embedded CPU, reducing the number of separate components required for sensing, signal conditioning, timing, and control.
The verified product listing identifies the device as an 8-bit, 24 MHz M8C PSoC 1 microcontroller with 4KB flash organized as 4K x 8. It is supplied in an 8-PDIP package and is positioned for embedded control applications requiring compact integration and configurable mixed-signal functionality. The 24 MHz operating speed supports timely control-loop and peripheral operation without requiring a larger processor package.
The CY8C24xxx architecture belongs to the PSoC 1 mixed-signal family, whose value is the combination of programmable digital and analog resources around an 8-bit CPU. Exact analog block assignments, memory maps, electrical limits, and peripheral functions require the manufacturer datasheet; they are not inferred here because those details are not included in the supplied verification data.
Typical design uses include industrial control interfaces, compact sensor-conditioning systems, temperature or light-control products, small motor-control loops, appliance controls, and communications-enabled embedded nodes. An 8-PDIP package also simplifies prototype construction and through-hole assembly, although production designs must consider mechanical spacing, programming access, and available board area.
Designers should confirm the exact pin functions, supply limits, clock requirements, programming method, and peripheral configuration in the CY8C24123 datasheet before layout or firmware release. The supplied distributor data does not establish a current manufacturer lifecycle designation, price ladder, or a complete technical specification set.
This page consolidates verified distributor facts, package information, application context, sourcing limitations, and a disciplined same-footprint replacement review. It intentionally avoids presenting unverified timing, memory, electrical, or lifecycle claims as guaranteed design data.

典型應用
CY8C24123-24PI 適用於 6 應用s: Compact Sensor Interface, Appliance Control Panel, Industrial Control Module, Temperature and Environmental Controller, Small Motor Control, Communications-Assisted Embedded Node.
Compact Sensor Interface
The CY8C24123-24PI fits compact sensor-interface products because it combines an 8-bit M8C control core, 24 MHz operation, and PSoC mixed-signal resources in an 8-PDIP package. A product can use the MCU for sensor selection, filtering, thresholding, state logic, and actuator control while reducing the need for separate analog and digital ICs. The verified data establishes the CPU speed and 4KB flash but does not specify analog block types, input counts, ADC resolution, or I/O capacity. Those details must be checked against the datasheet before assigning sensors or setting sampling requirements.
推薦
Appliance Control Panel
The CY8C24123-24PI is a reasonable candidate for appliance controls where a low-cost 8-bit MCU must manage buttons, indicators, relays, and timing functions. Its 24 MHz M8C core provides more scheduling headroom than a very low-speed simple controller, while 4KB flash supports a compact control program. The PSoC mixed-signal architecture may also support local sensing and control functions. Designers should confirm available digital I/O, analog inputs, timer resources, and supply voltage before fixing the panel architecture, especially when driving inductive loads or high-voltage interfaces.
推薦
Industrial Control Module
The CY8C24123-24PI can serve as the local controller in a small industrial module that coordinates discrete inputs, control outputs, status LEDs, and a simple communications interface. The 8-bit M8C architecture is appropriate for deterministic supervisory logic rather than demanding human-interface or high-throughput applications, and the 24 MHz clock allows responsive polling and timing. Its 8-PDIP package simplifies through-hole prototyping. Industrial deployment still requires verified operating-temperature limits, electrical isolation strategy, ESD protection, watchdog behavior, and communication peripheral details; those values are not present in the supplied evidence.
推薦
Temperature and Environmental Controller
The CY8C24123-24PI is suitable for basic temperature, light, or environmental monitoring products when the required control loop can be handled by an 8-bit M8C processor. The PSoC family concept allows configurable mixed-signal functions to coexist with control logic, while the 24 MHz clock supports responsive sampling and decision-making. The 4KB flash footprint favors compact control firmware rather than large data storage. Before selecting it, verify the required analog input topology, ADC or comparator resources, sensor excitation requirements, sampling rate, and calibration memory; the supplied distributor snippets do not provide those specifications.
推薦
Small Motor Control
The CY8C24123-24PI may fit small, low-power motor-control or actuator-control systems where the motor drive is handled by external power electronics. The 8-bit M8C core can sequence commutation, manage limit inputs, monitor feedback, and enforce timing, while the 24 MHz clock supports faster control tasks than many simple 8-bit entry-level devices. The PSoC mixed-signal architecture may assist with current or position sensing. However, exact timer outputs, capture channels, PWM resources, analog comparators, and operating-temperature limits must be verified before selecting the device for a safety-relevant or continuously running motor.
推薦
Communications-Assisted Embedded Node
The CY8C24123-24PI can serve as a supervisory node in a compact embedded network when its supported communication peripherals match the chosen protocol. The 24 MHz 8-bit M8C core is suitable for packet handling, address decoding, status monitoring, and local I/O control, while the 4KB flash supports a constrained firmware image. PSoC mixed-signal resources can potentially reduce the number of companion devices in measurement-and-control nodes. Designers must confirm UART, SPI, I2C, or other interface availability, pin multiplexing, protocol timing, and electrical levels in the datasheet; none of those peripheral details are confirmed by the supplied search snippets.

設計說明
Confirm the exact eight-pin assignment and package drawing before routing the PCB. The verified data identifies an 8-PDIP format but does not provide pin names, programming pins, supply pins, analog inputs, or ground locations. Do not rely on a generic PSoC 1 pinout from a different package variant; compare the manufacturer diagram, pin numbering, and keep-out requirements for the exact MPN.
Determine the device supply range, oscillator requirements, input thresholds, output drive, and analog current limits from the datasheet before adding decoupling or protection. The supplied listing confirms a 3.3 V-related listing in one result, but it does not provide the complete operating range or pin-level limits. Use only manufacturer-recommended power and bypass arrangements, and validate startup behavior across the full intended voltage and temperature range.
A related Cypress or Infineon PSoC family number is not automatically a drop-in substitute. Firmware, peripheral mapping, analog block behavior, clock pins, programming signals, and package assignment can differ even within one family. For any replacement, compare the pin table, memory map, interrupt vector behavior, startup code, and development-tool compatibility; preserve a hardware revision record and test the production firmware on the substitute before release.
