CY8C22113-24PI Overview
A microcontroller is a programmable semiconductor that integrates a CPU, memory, digital I/O, timers, and supporting peripherals on one device. The M8C architecture belongs to the embedded-controller hierarchy, which also includes 8-bit microprocessors, 16-bit and 32-bit microcontrollers, and application-specific processors. The CY8C22113-24PI sits at the entry level of that hierarchy: its 24 MHz clock and 2 KB flash capacity favor control-oriented logic rather than graphics, connectivity stacks, or data-intensive workloads.
Verified source data identifies the device as an 8-bit MCU with 2 KB flash, a 24 MHz operating speed, 256 x 8 data RAM, and an 8-DIP package measuring 0.300 inches across a 7.62 mm lead span. These values make it potentially useful for simple keypads, status indicators, timers, sensor interfaces, and compact household or industrial controllers. The limited memory must be considered carefully before adopting complex firmware, buffering, or protocol stacks.
The M8C family uses an 8-bit processing core intended to balance responsiveness with simple embedded-system economics. At 24 MHz, the device provides substantially more timing margin than basic low-speed control loops, while 2 KB of flash constrains program complexity. The exact operating voltage range, timer resources, digital I/O ratings, interrupt architecture, and clock options are not included in the supplied source snippets and therefore require confirmation from the manufacturer datasheet before design release.
Typical implementation uses require assigning ports to switches, sensors, displays, or actuators, programming flash-resident firmware, and adding power, decoupling, reset, and interface components around the eight-pin device. Because only eight leads are available, port allocation and multiplexing are especially important. A conservative design should reserve enough pins for its power rails and essential interfaces, then verify every external signal against the complete datasheet pinout.
The principal engineering trade-off is compactness versus expansion headroom. The 8-pin PDIP is useful for prototypes, through-hole production, and serviceable assemblies, but it provides fewer I/O options than larger microcontrollers. At 2 KB flash and 256 bytes of RAM, firmware should avoid libraries or buffering that consume substantial memory. Verify reset behavior, clock configuration, peripherals, electrical limits, and programming compatibility using the full manufacturer documentation.
This page consolidates verified distributor and archival part information into an application-oriented guide. It distinguishes confirmed facts from unavailable technical data, highlights the memory and package constraints, and avoids treating general cross-reference tools as proof that an unrelated MCU is a true drop-in replacement. That distinction is important because pin-compatible hardware may still require different firmware, peripherals, voltage limits, or programming tools.

Typical Applications
CY8C22113-24PI is suitable for 6 applications: Compact Sequential Control, Simple Keypad Interface, Temperature and Humidity Monitoring, LED Status Controller, Small Motor Control Interface, Battery-Powered Sensor Interface.
Compact Sequential Control
The CY8C22113-24PI fits compact sequential-control tasks because its 24 MHz M8C core provides timing margin while the 8-pin package limits the number of external signals available. A programmer can use flash-resident logic to sequence lamps, relays, actuators, or status indicators without introducing a larger controller. The main constraint is memory: 2 KB of flash and 256 x 8 bits of RAM favor a carefully bounded state machine. Before implementation, verify the complete pin assignment, I/O voltage, timer resources, and output drive limits from the manufacturer datasheet.
Recommended
Simple Keypad Interface
A keypad or small operator panel can suit the CY8C22113-24PI when debouncing and event handling remain compact. Its 24 MHz clock gives a practical margin for sampled inputs, while 256 x 8 bits of RAM constrains how many keys, history states, or display buffers can be managed concurrently. The eight-pin PDIP is useful for hand-built and serviceable through-hole controllers. Engineering review should confirm debounce timing, available ports, input thresholds, and whether an external driver is required for LEDs or displays.
Recommended
Temperature and Humidity Monitoring
The CY8C22113-24PI can support a small sensor-node controller when it periodically samples compatible digital sensors and forwards local status. Its 8-bit processor and 24 MHz operating speed are adequate for short measurement and control routines, but the 2 KB flash and 256 x 8 bits of RAM require minimal buffering and concise drivers. Use the limited pins carefully for sensor inputs, alerts, and communications. Voltage levels, conversion timing, and peripheral availability must be confirmed because the supplied verified snippets do not specify them.
Recommended
LED Status Controller
For a modest LED panel or status controller, the CY8C22113-24PI offers a low-pin-count through-hole implementation with enough clock speed for straightforward blinking, sequencing, and fault-indicator logic. The device should drive only the number of outputs supported by its verified GPIO and current limits; external transistors or LED drivers may be needed for higher current. Firmware must remain within 2 KB of flash and avoid unnecessary RAM buffering. Validate resistor values, duty-cycle requirements, and startup behavior during hardware bring-up.
Recommended
Small Motor Control Interface
The CY8C22113-24PI may serve as the command and sequencing controller for a small motor system, but it should not be assumed to drive motor current directly. Its 24 MHz processing rate supports closed-loop or timed control logic, while an external transistor stage isolates the MCU from motor transients. The 8-pin footprint and limited memory make a simple state machine appropriate. Verify whether the required PWM, protection, and fault inputs exist, and recalculate switching and thermal limits for the chosen driver.
Recommended
Battery-Powered Sensor Interface
In a battery-powered sensor interface, the CY8C22113-24PI can provide periodic measurement, threshold evaluation, and low-rate status output when firmware remains small. Its 24 MHz clock allows efficient event handling, but standby and active current data are not present in the verified snippets, so battery-life calculations cannot be finalized. Keep the controller inactive during long intervals if the datasheet permits. Confirm sleep modes, wake sources, operating voltage, and digital-input thresholds before selecting it for energy-limited duty-cycle designs.

Design Notes
Do not assign supply or I/O pins until the complete manufacturer pinout is obtained. The verified sources establish an eight-pin PDIP but do not identify individual functions. Check the operating-voltage range, input thresholds, output-drive limits, and absolute maximum ratings in the datasheet before connecting sensors or actuators. Add the manufacturer-recommended decoupling and ensure any external signal remains within the verified logic limits.
The 2 KB flash and 256 x 8 bits of RAM impose a hard firmware budget. Measure linked code and stack requirements during development, avoid copying libraries without checking their RAM cost, and keep buffering and protocol state deliberately small. A 24 MHz clock does not compensate for insufficient memory; complexity must be reduced before assuming the controller can support a larger protocol or user interface.
Reserve board space around the 0.300-inch, 7.62 mm PDIP footprint and follow the manufacturer land pattern rather than substituting a generic DIP footprint mechanically. Confirm hole diameter and row spacing from the package drawing. Provide a clear pin-1 orientation mark because the supplied sources do not document individual pin functions. Prototype with easily inspectable through-hole assembly when firmware and hardware validation are incomplete.
Compliance Information
The supplied verified snippets do not provide authoritative compliance declarations for the exact MPN. No compliance claim should be inferred from an undated distributor category or comparison page.
