description

The TSS400 Standard (TSS400-S1) sensor signal processor is an ultra-low power, intelligent, 12-bit A/D

converter (ADC) that has been preprogrammed with the Sensor Macro Programming Language (SMPL )

interpreter. This language allows fast, easy, and economical customization of the TSS400-S1 to a wide range

of sensor signal processing applications. The application specific programs that customize the operation of the

TSS400-S1 are stored in external EEPROMs along with any additional data required by the application. The

main components of the TSS400-S1 are a four-input multiplexed 12-bit ADC, a programmable constant current

source, an LCD driver capable of driving 56 segments using a 4-MUX drive scheme, two crystal controlled

independent timers, an on-board RAM, six output-only pins (R1 to R6), a 4-bit programmable I/O port (K1, K2,

K4, K8), and I C serial EEPROM communications. Operation of the TSS400-S1 is very adaptive because it is

controlled by a SMPL language program. These programs can be stored in an external EEPROM (standalone

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 of the SMPL language features are single-command EEPROM read and

EEPROM write operations, three levels of subroutines, a single-command A/D conversion instruction that

specifies the number of conversions and the type of conversion (either compensated or noncompensated) to

be made, and two reduced power consumption modes (DONE and OFF).
