Product details

PSoC1 configurable MCU with on-chip analog

The CY8C22345-24SXIT: Supply voltage spans 3 V to 5.25 V.

CY8C22345-24SXIT carries an active lifecycle status.

At 24 MHz the M8C core executes one instruction per two clock cycles in most cases.

Package and footprint: 28-SOIC wide-body

The 28-SOIC (0.295", 7.50 mm width) package is a surface-mount wide-body SOIC. The 24 I/O are accessible on standard 1.27 mm pitch. Supply decoupling should follow the PSoC1 layout guidelines: a 0.1 µF ceramic close to each Vdd/Vss pair, plus a bulk 10 µF capacitor near the package. The internal POR and LVD peripherals reduce external supervisor IC requirements.

Frequently asked questions

Is CY8C22345-24SXIT a drop-in replacement for CY8C22345-24SXI?

The suffix 'T' indicates Tape & Reel packaging. The CY8C22345-24SXI is the Tube-packaged variant. Both share the same silicon, 28-SOIC package, and electrical ratings. They are electrically identical; the only difference is the shipping medium.

Does CY8C22345-24SXIT require an external crystal for operation?

No. The CY8C22345-24SXIT has an internal oscillator, so it can operate without an external crystal. If tighter timing accuracy is needed, an external clock source can be used.

Is CY8C22345-24SXIT ROHS compliant?

Yes, the CY8C22345-24SXIT is ROHS3 compliant.

What is the closest functional second-source for CY8C22345-24SXIT?

Within the PSoC1 family, the CY8C29566-24AXIT offers a similar M8C core at 24 MHz but with more I/O (40), 12x14-bit ADC channels, and 4x9-bit DACs in a 44-pin TQFP package. It is a step up in analog capability and I/O count, not a pin-compatible drop-in. For a direct socket-compatible alternative with the same 28-SOIC footprint and 24 I/O, the CY8C29466-24PVXI is a closer match but differs in ADC resolution (12x14b vs 3x10b) and package (SSOP vs SOIC). Neither is an exact second-source; both require a board respin.
