Product details
Overview
DF3026X25V from Cypress Semiconductor is a PSoC® Programmable System-on-Chip™ integrating an M8C 8-bit Harvard-architecture microcontroller, four digital PSoC blocks, four Type E analog blocks, 8 KB flash, and 512 bytes SRAM. It operates from 2.4 V to 5.25 V across –40 °C to +85 °C and supports configurable GPIOs with 25-mA sink capability-used in capacitive touch sensing, motor control, and industrial sensor interface applications.
For engineers reviewing the DF3026X25V datasheet, DF3026X25V pinout, DF3026X25V application, or DF3026X25V equivalent, key selection criteria include its 24 MHz M8C core speed, dual 10-bit ADC support, programmable analog mux architecture, I²C/SPI/UART peripheral integration, and on-chip switch-mode pump for single-cell battery operation.
Technical Context
The DF3026X25V implements a fixed-function M8C CPU core (24 MHz max) with Harvard architecture and ISSP-based in-system programming. Its digital system uses four reconfigurable 8-bit PSoC blocks to synthesize timers, PWMs, UARTs, SPI masters/slaves, and CRC modules-all routable to any GPIO via global digital interconnect buses.
The analog system comprises four Type E blocks supporting comparators with 1.3 V reference or 8-bit DAC references, plus single/dual 10-bit 28-channel ADCs. An 8:1 analog input multiplexer and configurable analog bus enable capacitive sensing and flexible signal routing across up to 28 GPIOs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| M8C Core Speed | Up to 24 MHz - enables real-time control loops and high-speed serial communication without external clocking. |
| Flash Memory | 8 KB with 50,000 erase/write cycles - supports field firmware updates and EEPROM emulation for parameter storage. |
| SRAM | 512 bytes - sufficient for stack, variables, and small buffers in embedded sensor or HMI applications. |
| Analog Inputs | Up to 28 channels - allows full-port analog acquisition for multi-sensor systems or touchpad interfaces. |
| Digital I/O Drive | 25 mA sink / 10 mA source per GPIO - drives LEDs, small relays, or logic-level MOSFETs directly without external buffers. |
| Operating Voltage | 2.4 V to 5.25 V - compatible with standard 3.3 V and 5 V logic domains and industrial power rails. |
| Temperature Range | –40 °C to +85 °C - qualified for industrial and automotive under-hood environments. |
Pinout & Package
DF3026X25V is packaged in a 28-pin SSOP (Small Outline Integrated Circuit) with 0.65 mm pitch and exposed thermal pad. Pin functions are fully configurable via PSoC Designer software, with all GPIOs supporting analog mux input, digital I/O, and interrupt capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[7]–P0[0] | Analog column mux input | Supports up to eight analog inputs routed to internal ADC/comparator blocks; P0[3]/P0[1] also serve as integrating inputs for CapSense®. |
| P1[7]–P1[0] | I²C SCL/SDA, EXTCLK, ISSP | Hardware I²C master/slave (400 kHz), external clock input, and in-system serial programming interface. |

FAQ
What is the maximum operating frequency of the DF3026X25V M8C core?
The DF3026X25V features an M8C 8-bit Harvard-architecture processor with a maximum clock speed of 24 MHz. This frequency is achieved using the internal main oscillator (IMO) with ±2.5% accuracy, and it supports real-time execution of control algorithms, serial protocols, and sensor processing tasks without external clock sources. The DF3026X25V maintains this speed across its full operating voltage range of 2.4 V to 5.25 V.
Does DF3026X25V support capacitive touch sensing out of the box?
Yes, DF3026X25V natively supports capacitive touch sensing through its Type E analog blocks and dedicated analog mux architecture. Pins P0[3] and P0[1] are configured as integrating inputs for charge-transfer measurement, and the on-chip switched-capacitor blocks enable hardware-accelerated baseline tracking and noise rejection. Cypress's CapSense® user module in PSoC Designer provides certified firmware libraries for slider, proximity, and button implementations - all running directly on the DF3026X25V.
Can DF3026X25V operate from a single 1.2 V battery cell?
Yes, DF3026X25V can operate from a single 1.2 V battery cell using its integrated switch-mode pump (SMP). The SMP circuit generates a regulated internal supply voltage (typically ~3.3 V) from the 1.2 V input, enabling full functionality-including 24 MHz CPU operation, analog block usage, and GPIO drive-without external DC-DC converters. External components required are one inductor and two capacitors connected to the SMP pin, as specified in the DF3026X25V datasheet.
What development tools are required to program DF3026X25V?
DF3026X25V is programmed using Cypress's PSoC Designer™ IDE, a free Windows-based tool that includes a graphical user interface for configuring analog/digital user modules, C compiler with no code-size limits, and integrated debugger with in-circuit emulation. Programming is performed via the two-pin ISSP interface (SCLK/SDATA) using a MiniProg1 or MiniProg3 programmer. No JTAG adapter is required, and firmware updates can be deployed in-system through existing PCB traces.
Is DF3026X25V pin-compatible with other CY8C21x34 family members?
Yes, DF3026X25V is fully pin-compatible with CY8C21534 and CY8C21434 in the 28-pin SSOP package. All share identical pin assignments, electrical characteristics, and functional block mapping. Differences exist only in factory-programmed flash content and traceability identifiers - meaning DF3026X25V hardware designs accept CY8C21534 or CY8C21434 as direct replacements without layout or schematic modification.
