CY8C29466-24PVXI 概要
A PSoC 1 mixed-signal array is an 8-bit microcontroller that pairs an M8C CPU with a fabric of user-configurable analog and digital peripheral blocks. These arrays sit at the intersection of microcontroller and FPGA-class configurability, allowing on-chip op-amps, ADCs, DACs, PWMs, UARTs, and timers to be routed and parameterized in firmware. Within the broader semiconductor taxonomy, a PSoC 1 is a microcontroller (sub-class) under the integrated-circuit hierarchy, sitting alongside standard 8051 and M8C microcontrollers but distinguished by its analog/digital block array.
Key features include 32 KB (32K x 8) of in-system programmable Flash with ECC, 2 KB of SRAM, 24 GPIO with versatile drive modes, an on-chip full-speed USB 2.0 transceiver on selected SKUs, and up to 16 programmable analog blocks (PSoC analog blocks) for op-amps, ADCs, and DACs. The device supports in-system serial programming (ISSP) via the on-chip SWD/SPI port, a watchdog timer, sleep-mode current as low as a few microamperes, and an operating temperature range covering industrial-grade -40C to +85C.
The CY8C29466-24PVXI uses the M8C Harvard architecture with separate program and data address spaces. The Flash memory is read out of an 8-bit data bus and is in-system programmable through the PSoC programmer toolchain (PSoC Designer / PSoC Creator IDE support), while analog and digital blocks are wired through a configurable interconnect matrix. The 24 GPIO can be configured with multiple drive modes (pull-up, pull-down, open-drain, strong drive) for direct interface to peripherals without external glue logic.
Typical applications include human-machine interface (HMI) control panels, USB HID peripherals, sensor-signal conditioning front ends, motor-control signal-chain drivers, and industrial instrumentation. With 32 KB of Flash and 24 GPIO the device is well-suited to mid-complexity embedded designs that need mixed-signal conditioning on-chip.
When designing with this MCU, ensure that the IDE toolchain (PSoC Designer / MiniProg3 or KitProg) matches the silicon revision. Industrial grade variants have a -40C to +85C operating range; consider the CY8C29466-24PVXE extended-temperature option for wider thermal envelope.

主な用途
CY8C29466-24PVXI の用途: 6 件s: USB HID Peripheral (Keyboard / Mouse / Custom HID), Industrial Sensor Signal Conditioning, HMI Control Panel with Keypad and Display, Motor Control Signal Chain Driver, Battery-Powered Wireless Sensor Node, Medical Monitoring Device Signal Path.
USB HID Peripheral (Keyboard / Mouse / Custom HID)
The CY8C29466-24PVXI's 32 KB Flash and on-chip USB 2.0 full-speed transceiver make it well-suited for USB HID class peripherals including keyboards, mice, and custom HID devices. With 24 GPIO available, designers can directly interface key matrices, LED indicators, and capacitive touch sensors without external glue logic. The M8C core runs USB HID stacks comfortably within the 32 KB Flash budget. Placed at the USB connector end of a peripheral, the device handles enumeration, report generation, and suspend/resume power management. The PSoC1's configurable analog blocks allow direct sensor-signal conditioning on-chip, eliminating external op-amps for low-cost HID designs.
おすすめ
Industrial Sensor Signal Conditioning
The CY8C29466-24PVXI's configurable analog blocks (op-amps, ADCs, DACs) make it a strong fit for industrial sensor front ends that require on-chip amplification, filtering, and digitization of thermocouple, RTD, or strain-gauge signals. With 24 GPIO, the same MCU can drive 4-20 mA loops, digital isolators, and HMI displays. Industrial operating range of -40C to +85C supports factory-floor deployments. Compared to discrete op-amp + ADC solutions, the PSoC1 fabric reduces BOM count and PCB footprint, while the M8C core runs calibration and linearization algorithms in firmware.
おすすめ
HMI Control Panel with Keypad and Display
The CY8C29466-24PVXI suits HMI panels requiring keypad scanning, LCD/LED driving, and rotary encoder input. The 24 GPIO can multiplex a 4x4 matrix keypad (8 pins) plus a character LCD interface (6 pins) plus indicator LEDs and buzzer drive (4 pins), all without external logic. The 24 MHz M8C core handles debounce, menu navigation, and serial communication with a host controller. The configurable digital blocks (PWMs, timers, UARTs) reduce firmware overhead for backlight dimming and buzzer tone generation.
おすすめ
Motor Control Signal Chain Driver
The CY8C29466-24PVXI's configurable PWM blocks and analog blocks support low-cost brushed-DC and stepper motor control signal chains. With 24 MHz M8C timing and up to 16 digital blocks, the device generates multi-channel PWM, quadrature encoder input, and current-sense amplification on-chip. The 24 GPIO provide direct interface to H-bridge gate drivers and fault feedback. Industrial temperature range supports motor-control enclosures. Designers benefit from reduced external component count compared to traditional MCU + op-amp + gate-driver solutions.
おすすめ
Battery-Powered Wireless Sensor Node
The CY8C29466-24PVXI's low sleep-mode current and configurable peripherals make it a viable controller for battery-powered sensor nodes. The PSoC1 fabric can be configured to wake on GPIO change, ADC threshold, or timer events, then run a short measurement and transmit cycle before returning to sleep. The 32 KB Flash stores small protocol stacks and sensor calibration tables. With 2 KB SRAM, the device buffers measurement bursts. The 24 GPIO drive RF module control pins and sensor I/O without external mux logic.
おすすめ
Medical Monitoring Device Signal Path
The CY8C29466-24PVXI's configurable analog blocks support low-noise amplification and digitization of bio-signal inputs (ECG, EMG, SpO2) in low-cost medical monitoring peripherals. The 24 GPIO can drive LCD displays, button inputs, and isolated UART/SPI links to a host processor. With industrial temperature range and RoHS compliance, the device meets medical peripheral regulatory baselines (additional certification required at the system level). The PSoC1 fabric reduces the analog BOM, lowering total BOM cost for disposable and reusable medical peripherals.

設計ノート
The CY8C29466-24PVXI operates from 3.0-5.25 V. Place a 10 uF bulk + 0.1 uF ceramic decoupling capacitor pair as close as possible to the Vdd pin (pin 27) to suppress switching noise from the internal core. The M8C core draws up to 15 mA active at 24 MHz; ensure the upstream regulator can supply this peak without voltage droop. For USB applications, the internal USB transceiver requires a stable 3.3 V regulated rail.
At -40C to +85C industrial operating range, the SSOP-28 package has a thermal resistance (theta_JA) of approximately 100 C/W. Estimated: at 24 MHz active with 15 mA core current and 5 V supply, total power dissipation is about 75 mW, resulting in a 7.5C junction rise above ambient. For sealed enclosures with limited airflow, derate ambient temperature by 10-15C to keep junction within industrial limits.
Keep the SSOP-28 trace lengths under 25 mm for GPIO and analog signals to minimize parasitic capacitance. Place the 32.768 kHz crystal (if used for RTC) within 5 mm of the XIN/XOUT pins with a guard ring tied to ground. Use a 4-layer PCB with continuous ground plane beneath the device to reduce EMI from the 24 MHz CPU clock. The exposed pad (if present) must be soldered to the ground plane for thermal dissipation.
Do not confuse the CY8C29466-24PVXI (RoHS, industrial) with the CY8C29466-24PVXA (legacy non-RoHS) - they share the same datasheet but differ in lead finish. Verify the IDE toolchain matches the silicon revision: PSoC Designer supports legacy CY8C29xxx; PSoC Creator provides newer project migration paths. The ISSP programming pins (P1[0]/P1[1]) are shared with GPIO; isolate them during programming to avoid contention with external circuitry.
コンプライアンス情報
RoHS compliant per Infineon product page. The 'I' suffix denotes lead-free / RoHS-compliant variant vs the legacy 'A' suffix (CY8C29466-24PVXA) which is non-RoHS. Industrial temperature grade -40C to +85C.
