CY8C5287AXI-LP095 - PSoC 5LP ARM Cortex-M3 MCU | Infineon
MPN： CY8C5287AXI-LP095 ✓ 啟用中CY8C5287AXI-LP095 概覽
A PSoC (Programmable System-on-Chip) is a microcontroller variant that augments a conventional CPU core with universal analog blocks (op-amps, ADCs, DACs, comparators) and universal digital blocks (UDBs, timers, PWM, UART, SPI, I2C) that the developer can wire on-chip through a programmable interconnect. Architecturally, PSoC 5LP sits between a traditional MCU and an FPGA/CPLD: it offers hardware flexibility of an FPGA-like fabric while retaining the deterministic firmware model of an MCU. In the broader taxonomy it belongs to microcontrollers → 32-bit microcontrollers → ARM Cortex-M3 microcontrollers → programmable SoCs.
Key features include 256 KB Flash, 32 KB SRAM, 2 KB EEPROM, a 1 MSPS 12-bit SAR ADC, four 8-bit DACs, four op-amps, four programmable analog blocks, and up to 62 GPIO. The Cortex-M3 core with MPU, 32-channel DMA, and 80 MHz operation delivers strong deterministic performance for mixed-signal designs.
Typical applications include industrial sensor conditioning with on-chip op-amp gain stages, USB HID/CapSense user interfaces, motor control loops, programmable logic replacement using UDBs, and field-upgradeable embedded products. The wide 1.71-5.5 V range also lets the part run directly from a single Li-ion cell or a regulated 5 V rail.
When designing with this device, allocate sufficient ground and power decoupling (a 1 µF + 0.1 µF pair on each VDD pin) and follow Infineon PSoC Creator pinout guidance. Unused GPIO should be left floating or driven low, never tied to VDD, to avoid power-on glitches during programming.

典型應用
CY8C5287AXI-LP095 適用於 6 應用s: Industrial Sensor Signal Conditioning, CapSense Touch User Interface, USB HID / Composite Device, Brushless DC Motor Control, Programmable Logic Replacement (UDB-based), Field-Upgradeable Consumer Electronics.
Industrial Sensor Signal Conditioning
The CY8C5287AXI-LP095 fits industrial sensor signal-conditioning boards because it integrates four on-chip op-amps, four 8-bit IDACs, and a 12-bit 1 MSPS SAR ADC alongside the Cortex-M3 core. The 1.71-5.5 V supply tolerates 24 V industrial rails after a small LDO. Programmable analog blocks let designers build gain, filter, and bridge-completion stages without external analog ICs, reducing BOM and PCB area for sensor-conditioning applications.
推薦
CapSense Touch User Interface
PSoC 5LP's CapSense block pairs with the CY8C5287AXI-LP095 to implement up to 62 touch buttons, sliders, or proximity sensors with no external touch IC. The Cortex-M3's 80 MHz clock easily scans the CapSense sigma-delta converter and processes gesture algorithms in real time. Designers benefit from a 1.71-5.5 V supply, enabling battery-powered 3.3 V or single-cell Li-ion powered user-interface boards.
推薦
USB HID / Composite Device
The CY8C5287AXI-LP095's USB 2.0 full-speed block and 80 MHz core let it implement USB HID, CDC, and composite device firmware without an external PHY. Its 256 KB Flash accommodates USB descriptors, HID report tables, and CDC class stacks. The 32 KB SRAM and 32-channel DMA keep USB endpoints fed without CPU stalls, while PSoC Creator's USB middleware shortens time-to-prototype for HID peripherals.
推薦
Brushless DC Motor Control
With 24 UDBs and a Cortex-M3 running 80 MHz, the CY8C5287AXI-LP095 can generate center-aligned PWMs, decode Hall sensors or quadrature encoders, and run field-oriented control loops for small BLDC motors up to several hundred watts. The on-chip 12-bit ADC samples phase currents at 1 MSPS, enabling high-bandwidth current control. Designers get the motor drive plus the user interface in one chip, reducing board area.
推薦
Programmable Logic Replacement (UDB-based)
Each PSoC 5LP UDB delivers FPGA-like functionality: combinatorial logic, state machines, timers, and serial blocks. The CY8C5287AXI-LP095 with 24 UDBs can replace small CPLDs implementing glue logic, custom serial protocols, or parallel-to-serial conversion, all configured through PSoC Creator. This dramatically reduces BOM cost and PCB area versus separate CPLD + MCU solutions for protocol-bridging applications.
推薦
Field-Upgradeable Consumer Electronics
With 256 KB Flash and an in-system programmable Flash array, the CY8C5287AXI-LP095 supports bootloader-based field upgrades over UART, USB, or I2C for consumer appliances. Its wide 1.71-5.5 V supply lets it run from a single Li-ion cell or a 5 V USB rail. Designers can ship a single hardware revision and push new features, security patches, or UI updates to installed products.

主要差異化特點
- PSoC 5LP programmable analog and digital fabric on-chip (對比CY8C5468AXI-LP106)
- Higher 80 MHz Cortex-M3 clock speed vs 67 MHz parts (對比CY8C5667AXI-LP040)
- 32-channel DMA engine offloads Cortex-M3 core (對比CY8C5267AXI-LP051)
設計說明
Place a 1 µF + 0.1 µF ceramic decoupling pair on every VDD pin of the CY8C5287AXI-LP095, located within 3 mm of the package pin. Add a bulk 10 µF tantalum or ceramic near the supply pin of the regulator. The wide 1.71-5.5 V supply lets you run directly from a single Li-ion cell, but bypassing remains essential because UDB switching edges inject high-frequency noise into the analog fabric.
Route analog signals on a different layer than digital switching signals; use the dedicated VDDA pin with its own ferrite-bead-isolated analog LDO branch. The 100-pin TQFP has exposed thermal pad tied to ground - stitch at least 8 vias in the pad to a continuous inner ground plane to drop junction-to-ambient thermal resistance.
Do not leave unused GPIO floating during PSoC Creator boot - configure them in the .cydwr file with explicit 'Analog Hi-Z' or 'Pull-Down' settings, otherwise the boot ROM can latch into a debugger-detected mode. When migrating from CY8C5287AXI-LP095 to CY8C5288AXI-LP095, regenerate the project in PSoC Creator to update linker scripts because the Flash size differs.
