CY8C24094-24AXI - 8-Bit 24MHz PSoC MCU, 16KB Flash | 100-VFBGA
部品番号: CY8C24094-24AXI ✓ 生産中CY8C24094-24AXI 概要
A PSoC, or Programmable System-on-Chip, is an MCU architecture in which configurable analog and digital peripheral blocks are connected by a programmable interconnect array instead of being hard-wired to fixed pins. This lets one silicon device replace what would otherwise be an MCU, a timer, an ADC, an LCD drive stage and several discrete analog components on a mixed-signal control board. PSoC sits in the embedded microcontroller hierarchy alongside 8-bit and 32-bit MCUs, and is one member of the Cypress/Infineon PSoC 1 family.
Key characteristics of this device include an M8C processor core rated to 24 MHz, 16 KB of flash program memory, and an on-chip XRES pin supporting In-System Serial Programming (ISSP) and external reset control. The family members differ mainly in the amount of configurable analog and digital resource they integrate, so designers can size the peripheral set to the board rather than to a fixed pin map.
Technically, the M8C core uses a Harvard architecture with separate instruction and data spaces, a 16-bit instruction word, and an efficient sleep and watchdog management scheme suited to battery and handheld designs. The 100-VFBGA package keeps the footprint small for space-constrained industrial control, metering and IoT sensor designs, and its ball pitch supports fine PCB routing in dense analog/digital boards.
Typical applications for this device include industrial control panels, energy metering and utility-side sensing, motor and actuator control, smart building and IoT sensor nodes, security and access peripherals, and consumer low-power key-scan and small motor products.
Design consideration: PSoC 1 devices are programmed through the legacy ISSP interface rather than SWD or JTAG, so your toolchain, programmer and ISP header layout must be planned before the PCB is frozen. Confirm the ball map and exposed-pad connection directly in the manufacturer datasheet.
This page brings together manufacturer and distributor specifications for the CY8C24094-24AXI, pin-compatible PSoC 1 alternatives, side-by-side parameter comparison, and practical layout and programming guidance that the bare datasheet does not summarize in one place.

主な用途
CY8C24094-24AXI の用途: 6 件s: Industrial Control and HMI Panels, Energy Metering and Utility Sensing, IoT and Smart Building Sensor Nodes, Motor, Actuator and Relay Control, Security and Access Control Peripherals, Consumer Keypad, Remote and Appliance Controls.
Industrial Control and HMI Panels
The CY8C24094-24AXI fits supervisory control panels for machinery, pumps and small process skids, where the board must combine key scanning, indicator drive and a small amount of analog measurement in a single controller. The M8C 8-bit core at 24 MHz gives enough headroom for debounce plus display refresh plus a state machine, and the configurable analog and digital blocks let the designer place a comparator or op-amp function inside the chip instead of adding discrete parts. Because the device ships in a 100-VFBGA (6 x 6 mm) package, the controller footprint stays small enough for a compact panel-mounted board. Deployed units can be reflashed through the ISSP interface without rework, which simplifies field firmware updates on installed equipment.

Energy Metering and Utility Sensing
Utility-side metering boards benefit from the CY8C24094-24AXI because metering front-ends need accurate signal conditioning and long unattended service life rather than raw processing power. The M8C core at 24 MHz can run the measurement loop, calibration storage and communication stack for a single-phase or multi-channel compact meter, while the on-chip programmable blocks absorb input filtering and level shifting that would otherwise need external components. The 100-VFBGA (6 x 6 mm) footprint allows the metering section to sit close to the sensing analog front end, reducing trace length on sensitive signals. ISSP programming also supports secure in-field firmware updates on meters installed at remote customer premises.
おすすめ
IoT and Smart Building Sensor Nodes
The CY8C24094-24AXI suits connected sensing nodes in smart building and industrial IoT deployments where each node must condition a sensor, apply local filtering, and sleep for most of the day. The M8C processor supports sleep and watchdog handling for duty-cycled operation, and the PSoC programmable analog blocks can be configured to condition thermocouple, resistive or capacitive sensor inputs without a dedicated external analog IC. Its small 100-VFBGA (6 x 6 mm) package keeps the node board compact, which matters when the node is a small wall box or a battery-backed wireless module. If the wireless radio is a separate device, the ISSP header on this part is enough to handle final image programming and field updates.
おすすめ
Motor, Actuator and Relay Control
Compact motor and actuator controllers use the CY8C24094-24AXI where position sensing, current or speed feedback, and output switching all need to be handled by one microcontroller. At 24 MHz the M8C core can run closed-loop timing routines, capture encoder or hall signals, and supervise duty cycle, while the configurable digital blocks provide the timer and counter functions that drive the switching stage. Placing the controller in a 100-VFBGA (6 x 6 mm) package shortens the distance between the sensing inputs and the control logic, which reduces susceptibility to noise coupling from the power stage. For designs that need more analog channels for current sensing across several motors, the pin-compatible family members offer a straightforward scale-up.
おすすめ
Security and Access Control Peripherals
Keypad readers, credential readers and small access-control terminals often need secure key handling plus a small amount of I/O in a very compact board, and the CY8C24094-24AXI covers that tier well. The 8-bit M8C core executes the credential protocol and communication stack, while the programmable blocks handle LED indication, buzzer drive and keypad scanning with the same silicon, reducing the bill of materials for a sealed entry reader. The 100-VFBGA (6 x 6 mm) package fits inside a slim door hardware enclosure, and the ISSP interface allows programming in manufacturing plus secure key injection during production. Designs requiring larger flash for certificate storage should evaluate a higher-memory family member with the identical footprint.
おすすめ
Consumer Keypad, Remote and Appliance Controls
In consumer products such as key-scan overlays, remote controls and small appliance control boards, the CY8C24094-24AXI provides enough processing to run the whole human-interface layer without a separate logic IC. The 24 MHz M8C core handles debounce, matrix scanning, multi-press gestures and the indicator animation, and the PSoC architecture lets the LED drive or buzzer output be configured on-chip. Its 100-VFBGA (6 x 6 mm) package is small enough for a thin remote-control PCB, which reduces the internal volume that the product designer is trying to shrink. Where the appliance also needs motor or relay supervision, the family siblings with extra timer and analog blocks allow the same board to be reused.

設計ノート
The 100-VFBGA (6 x 6 mm) ball grid requires a fine-pitch land pattern that most low-cost two-layer boards cannot support reliably. Use the ball map and package outline in the manufacturer datasheet for the CY8C24x94 family as the land pattern authority, keep the exposed-pad connection exactly as specified, and check board warpage tolerance against the package drawing before committing to a substrate. Place the ISP programming header on the board edge so the XRES and ISSP lines are reachable without disassembly, and keep the ISP traces away from switching node and motor drive traces.
Because the PSoC 1 architecture lets analog blocks sit directly on chip, the analog inputs and digital outputs share the same ball grid, so placement discipline decides whether the analog path is clean. Route sensor and reference inputs on the quiet side of the board, keep them short, and ground-bounce-free by connecting analog ground to the exposed pad and analog supply pins with dedicated vias rather than through the digital return path. If the design adds a switching converter or relay driver on the same board, keep the switching loop physically separated from the sensor inputs and place filtering at the connector rather than at the MCU pin.
Estimated: with a 3.3 V rail and a measured active current of about 15 mA at 24 MHz, the CY8C24094-24AXI dissipates roughly 50 mW during active operation, which is well within the 100-VFBGA package capability without a dedicated heat spreader. The real thermal constraint is the solder-joint and via reliability of the dense ball array, not the silicon junction temperature. For battery designs, budget the sleep-mode current rather than the active current, and confirm the idle and wake-up numbers for your actual supply voltage in the manufacturer datasheet before sizing the cell.
The most common mistake with PSoC 1 designs is treating the ISP programming interface as a generic debug port. CY8C24094-24AXI is programmed in-system through the XRES pin with an ISSP-compatible programmer, so the ISP header must be routed with the correct pull-up and reference connections from the datasheet, and the programmer in production must be verified against this device family. A second common pitfall is underestimating the 16 KB flash budget for applications that also carry lookup tables, calibration data and a protocol stack. Plan the memory map early and use the larger family members if the estimate does not fit.
