Raspberry Pi System-on-a-Chip
Features
- PSOC part CY8C5267AXI-LP051
- Core: ARM Cortex M3
- Data Bus Width: 32 bit
- Maximum Clock Frequency: 67 MHz
- Program Memory Size: 128 kB
- Data RAM Size: 32 kB
- ADC Resolution: 12 bit
- Data RAM Type: SRAM
- Interface Type: I2C, USB
- Number of ADC Channels: 1
- Number of I/Os: 72 I/O

- Works on all Raspberry Pi cards with 40 pin GPIO (A+/B+/Pi2/Pi3/Zero)
- All 29 Raspberry Pi I/O lines are connected to the PSOC
- 3 of the lines are used for programming the PSSoC
- Configuration EEPROM
- Fuses on 3.3V and 5V power
- Two I/O connectors
- 14 + 16 = 30 I/O pins
Headers / Connectors
- Card marking
H1 - Programming Header
- Can program the card via this connector
- I use the KitProg part of CY8CKIT-059
- Note orientation of pin 1
| Programmer | H1 pin | Python IO Pin | Pi connector pin | WiringPi IO Pin |
|---|---|---|---|---|
| RESET | H1-3 | IO_22(Python) | Pi Pin 15 | GPIO.3(WiringPi) |
| SWDCLK | H1-4 | IO_23(Python) | Pi Pin 16 | GPIO.4(WiringPi) |
