Description

DVAL

NSRF (Not-Safe-to request frame status bit)

NSRE (Not-Safe-to request exposure status bit)

(1)

GLOB time seen on TDIG pin is only a fraction of the real GLOB time. GLOB program still extends after falling edge of

this signal.

OTP Memory

A non-volatile, one time programmable memory is provided on-chip. This is programmed with unique

device ID and temperature sensor calibration data from both temperature sensors. During

manufacturing, both temperature sensors are read out from the SPI registers in a controlled

environment temperature. The data is then written to the OTP memory.

The OTP memory is organized in 64 addresses of 8 bits each. Only the following registers are useful

for end users.

Bits

Description

Version

[7:0]

Highest bit denotes the version

TSENS1_CONV_MSB

[7:0]

Temperature sensor SPI value read when wafer

testing at 60

⁰C.

These values can be used for calibrating the

temperature sensor.

Data from top temperature sensor.

TSENS1_CONV_LSB

[7:0]

TSENS1_REF_MSB

[7:0]

TSENS1_REF_LSB

[7:0]

TSENS2_CONV_MSB

[7:0]

Data for bottom temperature sensor.

TSENS2_CONV_LSB

[7:0]

TSENS2_REF_MSB

[7:0]

TSENS2_REF_LSB

[7:0]

Chuck Temperature

[7:0]

Temperature of wafer during production testing.

Should be used for temperature calibration.

Resolution

[7:0]

Denotes 8 k or 14 k resolution.

0b 0000 0000 = Virgin state

0b 0000 0001 = 14 K full resolution

0b 0000 0011 = 8 K resolution

0b 0000 01xx = 14 K full resolution

0b 0000 11xx = 8 K resolution

0b 0001 xxxx = 14 K full resolution

0b 0011 xxxx = 8 K resolution

0b 01xx xxxx = 14 K full resolution

0b 11xx xxxx = 8 K resolution
