TSS400-S1

POWER PROGRAMMABLE HIGH-PRECISION

SENSOR SIGNAL PROCESSOR

SLMS001 – D4071, JANUARY 1993

description (continued)

The TSS400-S1 is designed to meet a wide variety of sensor systems applications including those that require

short time-to-market and rapid and/or frequent programming updates. Since the TSS400-S1 does not require

mask programming, it can be purchased in any quantity. Some typical applications include:

•

measurements of temperature, pressure, acceleration, gas content, magnetic field, relative humidity,

speed, direction, and volume

•

measurements requiring calculation, control, and/or warning functions

measurements where temperature compensation is required for accuracy

measurements where software calibration and linearization is desirable

These sensor systems can be found in many types of applications including home appliances, industrial control

subsystems, HVAC systems and instrumentation, portable instrumentation, consumer products, automotive

products, or anywhere precise (12-bit), ultra-low power (12 µA – 15 µA, TYP), intelligent A/D conversion is

essential.

TheTSS400-S1isavailableintwotemperatureranges. TheTSS400CFN-S1ischaracterizedforoperationfrom

0°C to 70°C. The TSS400AFN-S1 is characterized for operation from –40°C to 125°C.

initialization and power up

Initialization is started by hardware in two ways:

•

Power up: The voltage V

oscillator has started operation. This may take from 1 to 6 seconds.

is switched on (cold start). The CPU starts to work at PC 000 after the internal

INITN pin: If the INITN pin is held low (switched to ground) for more than 10 µs (when this occurs during

program execution it is called a warm start). The CPU starts operation at PC 000 when the INITN pin is

released to V

potential.

Table 1 lists the TSS400-S1 register contents after a power up or an INITN pin initialization.
