description

The TSS400-S2 sensor signal processor is an ultra-low power, intelligent, 12-bit analog-to-digital converter (ADC) that has been preprogrammed with the Sensor Macro Programming Language

(SMPL^TM) interpreter. This language allows fast, easy, and economical customization of the TSS400-S2 to a wide range of sensor signal processing applications. Some of the typical applications include:

Temperature measurements with calculating, controlling, and warning features
Pressure and acceleration measurements
Timers with control functions
Intelligent keyboard and display drivers

The application-specific programs that customize the operation of the TSS400-S2 are stored in external EEPROMs along with additional data required by the application. The main components of the TSS400-S2 are a four-input multiplexed 12-bit ADC, a programmable constant-current source, an LCD driver capable of driving 56 segments using a four-multiplex drive scheme, two crystal-controlled independent timers, an on-board RAM, six output-only terminals (R1 to R6), a 4-bit programmable I/O port (K1, K2, K4, K8), and I²C serial EEPROM communications. Using the TSS400-S2 is very easy because it is controlled by a SMPL language program. These programs can be stored in an external EEPROM (stand-alone mode) or stored in a host computer (slave mode). The SMPL language is a powerful, easy-to-learn, and easy-to-use macro language. Some SMPL language features include single-command EEPROM read and EEPROM write operations, three levels of subroutines, a single-command A/D conversion instruction that specifies the numbers of conversions and the types of conversions (either compensated or noncompensated), and two reduced power consumption modes (done and off).
