Product details
Overview
CY8C28623-24LTXIT from Infineon Technologies (formerly Cypress Semiconductor) is a programmable System-on-Chip (PSoC® 1) integrating an M8C 8-bit Harvard-architecture CPU, 16 KB flash, 1 KB SRAM, up to 12 digital PSoC blocks, and up to 16 analog PSoC blocks - enabling configurable mixed-signal system integration in a single 48-pin TQFP package. It operates from 3.0 V to 5.25 V at up to 24 MHz and supports industrial temperature range (–40 °C to +85 °C), used in embedded sensor interface and motor control subsystems.
For engineers reviewing the CY8C28623-24LTXIT datasheet, CY8C28623-24LTXIT pinout, CY8C28623-24LTXIT application, or CY8C28623-24LTXIT equivalent, key selection criteria include its 24 MHz M8C core speed, 14-bit SAR ADC capability (up to 142 ksps), dual hardware I²C support (0–400 kHz), on-chip switched-mode pump for 1.5 V operation, and configurable GPIO drive modes (25 mA sink / 30 mA analog output).
Technical Context
This PSoC 1 device implements a fixed-function M8C CPU core with Harvard architecture, supporting 8×8 multiply and 32-bit accumulate operations. Its digital system uses up to 12 reconfigurable 8-bit digital blocks connected via global interconnects to all 44 GPIOs, enabling synthesis of UARTs (up to 3 full-duplex), PWMs (8-/16-bit), timers, CRC, and PRS modules.
The analog system integrates up to 12 rail-to-rail analog blocks offering programmable gain amplifiers, comparators, filters, and ADC/DAC configurations - including dedicated SAR ADC with sample-and-hold and up to four delta-sigma ADCs. Clocking includes ±2.5% 24 MHz IMO, optional 32.768 kHz ECO for RTC, and internal low-power ILO for watchdog/sleep.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply input | Accepts 3.0–5.25 V; powers core, digital, and analog systems; requires local 0.1 µF decoupling. |
| VSS | Ground reference | Digital and analog common return; must be low-impedance connection to minimize noise coupling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C28443-24LTXI | Fewer analog blocks (8 vs. 12), no delta-sigma ADC support, same M8C core and memory. | Limited analog channel count and no multi-ADC synchronization - suitable for simpler sensor nodes without simultaneous acquisition. | Select when analog resource demand is ≤8 blocks and delta-sigma functionality is unnecessary. |
| CY8C28643-24LTXI | Full analog block complement (12), adds 4 delta-sigma ADCs and enhanced CapSense® support. | Enables higher-resolution multi-channel sensing and advanced touch algorithms - requires additional design validation for delta-sigma timing constraints. | Select when simultaneous delta-sigma acquisition or advanced capacitive sensing is required. |
Compared with CY8C28443-24LTXI, this part delivers greater analog flexibility and real-time acquisition capability; compared with CY8C28643-24LTXI, it trades delta-sigma ADCs for cost-sensitive designs where SAR-only performance suffices.

FAQ
What development tools are required to program CY8C28623-24LTXIT?
PSoC Designer™ (free Windows IDE) is the official development environment, providing drag-and-drop peripheral configuration, API code generation, and full-speed emulation. Programming requires MiniProg1 or MiniProg3 hardware debuggers, which connect via ISSP interface using dedicated PSoC pins (e.g., RST, SCLK, SDATA). No third-party toolchain support is provided.
Does CY8C28623-24LTXIT support USB connectivity?
No, CY8C28623-24LTXIT does not include USB transceivers or dedicated USB hardware. It supports UART, SPI, and I²C for host communication. For USB-capable PSoC devices, refer to the PSoC 3 or PSoC 4 families (e.g., CY8C3866AXI-068 or CY8C4247LQI-BL483), which integrate full-speed USB 2.0 PHY and controller.
Can the on-chip 24 MHz oscillator meet timing-critical UART baud rates?
Yes, the internal main oscillator (IMO) is specified at ±2.5% accuracy over voltage and temperature, sufficient for UART operation up to 115.2 kbps with standard 8N1 framing. For higher precision (e.g., automotive CAN or 1 Mbps UART), use the optional 32.768 kHz crystal with PLL to derive a stable 24 MHz clock, reducing baud rate error to <0.1%.
Is EEPROM emulation supported, and how is it implemented?
Yes, EEPROM emulation is natively supported in flash memory using Cypress's Emulated EEPROM User Module. It provides byte-addressable nonvolatile storage with wear-leveling across designated flash sectors, rated for 100,000 write cycles per logical address. The module handles background erase/write sequencing and data integrity checks without CPU intervention during normal operation.
