Product details
Overview
CY8C24223A-24PVXAT from Cypress Semiconductor is a programmable 8-bit Harvard-architecture PSoC® SoC featuring an M8C CPU core running at up to 24 MHz, 4 KB flash, 256 bytes SRAM, and integrated analog/digital blocks including six analog and four digital PSoC blocks. It operates from 2.4 V to 5.25 V (or down to 1.0 V with on-chip switch-mode pump), supports industrial temperature range (–40 °C to +85 °C), and targets embedded control applications requiring mixed-signal reconfigurability.
For engineers reviewing the CY8C24223A-24PVXAT datasheet, CY8C24223A-24PVXAT pinout, CY8C24223A-24PVXAT application, or CY8C24223A-24PVXAT equivalent, key selection criteria include its 28-pin PDIP package, 24 MHz IMO clock accuracy (±5%), I²C/SPI/UART peripheral support, GPIO drive strength (25 mA sink), and analog subsystem capability (14-bit ADC, PGA, comparator).
Technical Context
The device implements a fixed-function M8C CPU core with Harvard architecture, supporting 8×8 multiply and 32-bit accumulate operations. Its digital system comprises four 8-bit digital PSoC blocks configurable as timers, PWMs, UART, SPI, I²C (slave/multi-master), CRC, and PRS modules - all routable to any GPIO via global digital interconnect.
The analog system integrates six rail-to-rail analog PSoC blocks enabling programmable gain amplifiers, 14-bit SAR ADCs, 9-bit DACs, filters, and comparators. Analog inputs are available on eight GPIOs (plus four restricted), with two 30 mA analog outputs supported across all GPIOs.

FAQ
What development tools are required to program the CY8C24223A-24PVXAT?
PSoC Designer™ (free Windows IDE) is the official development environment, providing drag-and-drop hardware configuration, C compiler, and debug support. Programming requires MiniProg3 (CY8CKIT-002) or MiniProg1 (CY3217), both supporting ISSP via two-wire interface. No external programmer hardware is needed beyond these certified tools.
Does the CY8C24223A-24PVXAT support true hardware I²C master functionality?
Yes - it implements full I²C slave, master, and multi-master modes up to 400 kHz using dedicated digital resources. The I²C module handles arbitration, clock stretching, and ACK/NACK automatically, freeing the CPU from bit-banging overhead. External pull-up resistors (2.2 kΩ typical) are required on SDA/SCL lines per I²C specification.
Can the on-chip switch-mode pump (SMP) power analog blocks during ultra-low-voltage operation?
Yes - the SMP generates regulated 2.4 V from 1.0–1.8 V input, enabling full analog subsystem operation (including PGA, ADC, and reference) even when VDD drops below 2.4 V. This allows continuous sensor monitoring during battery brown-out conditions without external boost converters.
Is the 14-bit ADC performance affected by temperature or supply variation?
The 14-bit SAR ADC uses an internal precision bandgap reference and auto-calibration routines. Over the full industrial temperature range (–40 °C to +85 °C) and supply range (2.4–5.25 V), INL remains ≤±4 LSB and DNL ≤±1 LSB - verified in production test and documented in the DC Electrical Characteristics table of Rev. *W datasheet.
