The chassis technology It's based on the Toshiba TA7698AP which is a Pioneer in Monochip Video Chroma Deflection combined ASIC IC.
And a SGS M431BB Tuning control IC which isn't a Microcontroller but an ASIC for tuning / search / remote TV control system.
SGS is Società Generale Semiconduttori - Aquila Tubi E Semiconduttori (SGS-ATES, "Semiconductor General Society - Tubes and Semiconductors Aquila"), later SGS Microelettronica, a former Italian company now merged into STMicroelectronics
SGS Microelettronica and Thomson Semiconducteurs were both long-established semiconductor companies. SGS Microelettronica originated in 1972 from a previous merger of two companies:
- ATES (Aquila Tubi e Semiconduttori), a vacuum tube and semiconductor maker headquartered in the Abruzzese city of l'Aquila, who in 1961 changed its name into Azienda Tecnica ed Elettronica del Sud and relocated its manufacturing plant in the outskirts of the Sicilian city of Catania
- Società Generale Semiconduttori (founded in 1957 by Adriano Olivetti).
TA7698AP TOSHIBA INTEGRATED CIRCUIT
TECHNICAL DATA TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT
VIDEO—CHROMA-DEFLECTION SYSTEM FOR A COLOR TELEVISION (PAL, NTSC)
The TA7698AP combines a PAL/NTSC Video— Chroma subsystem and a Deflection combination on a single monolithic integrated circuit to provide a PAL or PAL/NTSC color television.
This device includes a Video amplifier , PAL ,and NTSC color demodulator these are designed
to provide color differential signal outputs, and improved Sync—separator, Horizontal
oscillator with saw tooth wave type AFC, Horizontal pre-driver with X'ray protection include
circuit, Vertical oscillator and Vertical Predriver in a dual-in-line type plastic package.
