APPENDIX A:

DEVICE DELTA

A.1

Delta from CAP1106 to CAP1206

The CAP1206 is pin- and register-compatible with the CAP1106, with the exception of the GAIN[1:0]

bits and ALT_POL bit.

1. Revision ID set to 00h.

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

3. 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").

4. 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").

5. Increased supply voltage range for 5V operation.

6. Increased operating temperature range from 0°C - 85°C to -40°C to 125°C.

7. Removed proximity detection gain (GAIN[1:0] bits).

8. Removed ALERT pin configuration (ALT_POL bit).

9. Register additions are shown in Table A-1, "Register Delta".
