TMS0952NC Circuito Integrato Texas Instruments
MCU Texas per calcolatrici portatili
With the TMS0952 Texas Instruments introduced in the year 1975 the first "real" single-chip calculator design based on the TMS1000 family. In opposite to the TMS0102 with the discrete segment- and digit-drivers or the TMS0803 with the external digit-drivers this design controlled the seven-segment display directly. The chip integrates 8192-bit read-only program memory (ROM), a 256-bit random-access memory (RAM) and a decimal arithmetic logic unit as well as control, timing, and output decoders plus drivers for the display. This adds up to an overall complexity of roughly 8000 transistors.

Due to a flexible design concept with a programmable ROM some design variations appeared. Compare this IC with the TMS0954 and the later TMS0972. Please find a pictures with all three calculator chips here.
A typical calculator built around the TMS0952 family performs the four basic functions +,-,*,: and adds the %-function and a four-key memory, the later TMC0980 allowed for both scientific and financial calculators with up to 40 keys.
