MSX-Engine

An MSX-ENGINE chip is a specially developed <a href="/facts/Integrated_circuit/fjn6vg7C">integrated circuit</a> for home computers that are built according to the <a href="/facts/MSX/mthwra8a">MSX</a> specifications. 
Generally, such a chip combines the functions of many separate, older/simpler chips into one. This is done to reduce required circuit board space, power consumption, and (most importantly) production costs for complete systems.
The first MSX-Engine chip, the T7775 operated next to a standard <a href="/facts/Zilog/sB6jH5vw">Zilog</a> <a href="/facts/Z80/Jeqe2h55">Z80</a>-clone chip, the main <a href="/facts/CPU/Jxp1bqMV">CPU</a> of the system, but most later versions of the engine also included the Z80 (clone) CPU in a same single chip package. The S-1990, is a special case, as it's not really an MSX-Engine, but a chip that was used as "<a href="/facts/Glue_logic/zIvALrMX">glue logic</a>" between the MSX-engine and an external <a href="/facts/R800_(CPU)/xBRxYoWk">R800</a> CPU.
The T9769 is used in MSX 2 computers, while in MSX 1 computers mostly the T7775 and T7937 are used. You can also find the S-1985 and S-3527 in these systems. After the MSX 2 generation (from MSX2+ onwards) <a href="/facts/Toshiba/QHRaw8Tr">Toshiba</a> took over the complete production of MSX engine chips. The last generation of MSX, the Turbo-R used the <a href="/facts/NEC/YnlUsMBA">NEC</a> S-1990 "TurboR bus controller" together with a <a href="/facts/R800_(CPU)/xBRxYoWk">R800</a> CPU.
MSX engine chips from Yamaha were mostly used in MSX-computers from <a href="/facts/Sony/7x4tCtBd">Sony</a> and <a href="/facts/Philips/Xp4uczGg">Philips</a>, while the Toshiba chips were mostly used in computers from <a href="/facts/Sanyo_Electric/kk7BSfKF">Sanyo</a> and <a href="/facts/Matsushita_Electric_Industrial_Co.%2c_Ltd./TqkBQmgj">Matsushita</a> (Panasonic/National).
