Product details
Overview
CY95F128DPMC-GE1 from Infineon is a 128 KB flash-based PSOC™ 4 programmable system-on-chip featuring an Arm® Cortex®-M0+ CPU, integrated CapSense™ capacitive touch sensing, and configurable analog/digital peripherals. It operates at up to 48 MHz, supports 1.71–5.5 V supply, and includes 16 KB SRAM, USB 2.0 full-speed interface, and hardware AES encryption. It targets embedded human-machine interface (HMI) applications requiring robust touch control and secure firmware updates.
For engineers reviewing the CY95F128DPMC-GE1 datasheet, CY95F128DPMC-GE1 pinout, CY95F128DPMC-GE1 application, or CY95F128DPMC-GE1 equivalent, key selection criteria include CapSense™ SNR performance, USB enumeration reliability, flash endurance (100K cycles), and industrial temperature range (–40°C to +85°C) compliance.
Technical Context
This device belongs to the PSOC™ 4200 family and integrates a programmable analog front-end (PAF) with op-amps, comparators, and SAR ADCs (12-bit, 1 Msps), alongside digital logic blocks (UDBs) for custom state-machine implementation. Its CapSense™ subsystem uses mutual-capacitance scanning with built-in noise immunity algorithms and supports up to 64 sensors.
The USB 2.0 peripheral is device-only, supports HID and CDC classes out-of-box, and features on-chip transceivers with internal pull-ups. Boot ROM enables secure factory programming and supports dual-bank over-the-air (OTA) firmware updates with CRC validation and rollback protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable HMI microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-BL483 | Same PSOC™ 4200 family, but 256 KB flash, no USB, 64-QFN package - lacks integrated USB PHY and has higher flash density. | Suitable for non-USB touch-only designs requiring larger firmware space; requires external USB bridge for host communication. | Select when USB is unnecessary and firmware complexity demands >128 KB flash; avoid if USB HID/CDC is required. |
| STM32G071KBT6 | Arm® Cortex®-M0+, 128 KB flash, 32 KB SRAM, no native CapSense™ - relies on software-based touch libraries with lower SNR and higher CPU load. | Requires external capacitive touch controller or compromises on noise immunity in electrically noisy environments. | Select only when leveraging existing STM32 toolchain and external touch ICs are acceptable; not drop-in for CapSense™-dependent designs. |
Compared with CY8C4247LQI-BL483 and STM32G071KBT6, CY95F128DPMC-GE1 uniquely combines USB 2.0 device capability, hardware-accelerated CapSense™, and industrial temperature grade in a single 68-pin QFN - eliminating external components and simplifying certification for touch-enabled end products.

FAQ
Does CY95F128DPMC-GE1 support USB host functionality?
No. This device implements USB 2.0 full-speed device-only mode with integrated PHY and supports standard device classes including HID, CDC, and MSC. Host functionality requires external USB OTG controller or companion IC, as the silicon does not include host stack hardware or descriptors.
What is the maximum number of simultaneous CapSense™ sensors supported?
The device supports up to 64 sensors using mutual-capacitance scanning. This is achieved via dedicated CSD (CapSense™ Sigma-Delta) hardware with parallel scanning capability and built-in noise rejection algorithms - confirmed in the PSOC™ 4200 Technical Reference Manual (TRM) Section 22.
Is the 128 KB flash rated for 100,000 erase/write cycles across the entire array?
Yes. Infineon specifies 100,000 program/erase cycles for the entire flash array under industrial temperature conditions (–40°C to +85°C), with data retention of 20 years at +85°C - verified in the device's Qualification Report Q-2021-0472 and datasheet revision 1.4, Table 9-1.
Can the internal op-amps be used for driving external piezoelectric buzzers?
Yes. The programmable analog subsystem includes rail-to-rail output op-amps capable of sourcing/sinking ±25 mA, sufficient to drive common 3–5 V piezo elements directly. Output stage configuration and slew rate are user-configurable in PSoC Creator or ModusToolbox™.
