• Manufacturer Part Number: cy8c42123
• Description: Power Psoc? Devices
• Manufacturer: Cypress Semiconductor Corporation.

The 32-pin QFN part is for the CY8C42000 On-Chip Debug (OCD) PSoC device.
Note This part is only used for in-circuit debugging. It is NOT available for production .
32-Pin OCD Part Pinout (QFN**)
Document 38-12034 Rev. *C
LEGEND I = Input 5V Only, O = Output 5V Only, HV = High Voltage, NC = No Connection, OCD = On-Chip Debug.
* These are the ISSP pins, which are not HighZ at POR (Power On Reset). See the Power PSoC Mixed-Signal Array Technical Reference Manual for details.
**The QFN package has a center pad (CP) that must be connected to ground (Vss).
