APPENDIX A:

DEVICE DELTA

A.1

Delta from CAP1133 to CAP1203

1. Revision ID set to 00h.

2. Pinout changed. LED pins removed. Added GND pin as ground slug is no longer used for ground

connection.

3. Reduced package size from a 10-pin 3mm x 3mm DFN to an 8-pin 2mm x 3mm TDFN.

4. Added Power Button feature (see Section 4.5, "Power Button").

5. Added ACAL_FAIL bit to flag analog calibration failures (see Section 5.2, "Status Registers") and

ACAL_FAIL_INT bit to control analog calibration failure interrupts (see Section 5.6, "Configuration

Registers").

6. Added BC_OUT bit to flag calibration failures regarding base counts out of limit (see Section 5.2,

"Status Registers") and BC_OUT_RECAL and BC_OUT_INT bit to control base count out of limit

behavior and interrupts (see Section 5.6, "Configuration Registers"). Added Base Count Out of

Limit Register to indicate which sensor inputs have base counts outside the operating range (see

Section 5.16, "Base Count Out of Limit Register").

7. Increased supply voltage range for 5V operation.

8. Removed proximity detection gain.

9. LEDs removed.

10. Removed ALERT pin configuration.

11. Register set change as shown in Table A-1, "Register Delta".
