Custom Mixed Signal Industrial ASICs
A selection of custom mixed signal Industrial ASICs from Custom Silicon Solutions, including a Non-Volatile Elapse Time & Event Counter, a Micro-Power 555 Programmable Timer, a 10 Bit, 36V Current DAC, a 15W Thermal Controller and an 8-bit Microcontroller.
Non-Volatile Elapse Time & Event Counter
This ASIC is a non-volatile elapse time counter and an event counter. In the elapse time counter mode it counts time (hours, minutes, and seconds) when power is applied. At power-down it stores the current time in non-volatile memory. At power-up, that time is restored to the counter and time counting continues. In the event counter mode, it simply counts pulse inputs and stores the count in non-volatile memory at power-down. At power-up that count is restored to the counter and event counting continues. Outputs are via 7-segment LCD drivers.
Micro-Power 555 Programmable Timer
The CSS555C IC is an advanced version of the popular 555 timer. It contains a six-decade programmable counter to allow time delays ranging from microseconds to days. The analog circuits are temperature compensated for good stability. An internal timing capacitor is included to minimize the number of external components. It draws 10X less current than all other 555 timer devices. This device is an “off-the-shelf” standard product available for purchase.
10 Bit, 36V Current DAC
This ASIC is an industrial grade, 10-bit digital-to-analog converter. It provides an output current that ranges from approximately 0mA to 2mA. It is fabricated in an advanced, high voltage BiCMOS process, allowing operation from ±5V to ±18V. The output current has excellent linearity over temperature and is guaranteed monotonic. This device includes a matched feedback resistor for voltage applications. A full-scale adjustment and a bipolar offset are also provided.
15W Thermal Controller
This device is used in precision clock generators to hold the temperature of a crystal constant. It incorporates the heating element, temperature sensor and error amplifier into one IC. An internal DAC and EEPROM set the temperature. A 15V power FET acts as the heater. The maximum current is programmable and stored in the EEPROM.
8 Bit Microcontroller
This device is a direct replacement for a standard microcontroller. It is fully static, high speed and draws about 3X less power than the original version. Program storage is provided by a 4K ROM. It contains a 128 byte SRAM, memory mapped I/O, a 16 bit counter/timer and a dedicated serial interface.
