Overview
The CY8C24123A-24SXI is an 8-bit microcontroller from the PSoC 1 family, featuring the M8C core operating at up to 24 MHz. It includes 4 KB of Flash program memory and 256 bytes of SRAM. The device provides six analog PSoC blocks supporting up to 14-bit ADCs and 9-bit DACs, alongside four digital PSoC blocks for timers, counters, PWMs, UART, SPI, and I2C interfaces. It operates within a voltage range of 2.4 V to 5.25 V and supports industrial temperatures from -40 °C to +85 °C in an 8-pin SOIC package.
Feature Summary
- Configurable analog and digital system-on-chip architecture allowing custom peripheral creation
- Integrated M8C processor with Harvard architecture and hardware multiply/accumulate unit
- Flexible GPIO configuration with multiple drive modes and interrupt capabilities on all pins
- On-chip switch-mode pump enabling operation from single-cell battery sources
Applications
- Industrial control systems requiring programmable analog signal conditioning
- Battery-powered devices utilizing the internal switch-mode pump for voltage boosting
- Embedded sensor nodes needing configurable ADC/DAC resources
- Communication gateways implementing I2C, SPI, or UART protocols
Procurement Notes
Verify component authenticity through authorized Infineon distributors. Confirm RoHS compliance status as specified in the datasheet. Ensure handling procedures account for moisture sensitivity level 3 requirements during storage and reflow soldering processes.
Selection Notes
Select this part when design requirements demand high configurability of mixed-signal peripherals within a compact 8-pin footprint. The CY8C24123A-24SXI is suitable for applications needing precise analog control combined with flexible digital logic, replacing multiple discrete components.
Part Context
This component belongs to the CY8C24x23A series of PSoC 1 devices. It is derived from the previous CY8C24x23 generation, offering optimized low-power performance and support for lower voltage operation starting at 2.4 V while maintaining compatibility with existing development tools.
Replacement Considerations
Direct pin-compatible substitutes within the same package include CY8C24123A variants with different speed grades or temperature ranges. Cross-family replacements require architectural review due to differences in PSoC block counts and memory sizes.
