arcade machines. The TMS5220 was also used in the Androbot, Inc. Topo line of robots, starting with Topo II and Topo III in 1984. Superseded by TMS5220C in 1983/1984. Uses the 'final' chirp table. HP 82967A Speech synthesis module, adding 1500-word vocabulary to Series 80 computers. 1983 TMS5220C (after 1985: TSP5220C): has the two NOP commands the parallel FIFO interface reworked to control speech rate, added external full reset; minor change apparent to the way energy values affect unvoiced frames. Otherwise identical, pin-compatible, and a drop-in replacement to the TMS5220. Used on the Atari arcade games Indiana Jones and the Temple of Doom, 720°, Gauntlet, Gauntlet II, A.P.B., Paperboy, RoadBlasters, Vindicators Part II, and finally Escape from the Planet of the Robot Monsters. Also used on the IBM PS/2 Speech Adapter and the Pacific Educational Systems RS-232 Speech adapter. Manufactured into the early 1990s. 1985 TSP50C50: CMOS, uses LPC-12 instead of LPC-10, uses TMS60C20 256Kb/32KiB serial ROM instead of TMS6100. Uses 'D6' LPC tables and chirp tables, which were common for the whole TSP50Cxx series. Has built in low-pass analog filter. Manufactured into the early 1990s. 1986 TSP50C40 (later MSP50C40): TSP50C50 plus a simple 8-bit microcontroller with on-chip mask ROM. Was used in a number of TI's consumer division products. was named CM54129/CM54169 for the speak&music. 1987 and later Several other TSP50Cxx products, which added more ROM/ram, did away with the serial interface entirely, etc. The TSP53C30 microcontroller product emulates a TMS5220 PE-LPC, but also has support for D6 LPC as well as PCM sound output. After about 1997, the TSP non-microcontroller line was phased out in favor of speech-specific members of the MSP line, which have microcontrollers. In October 2001, the rights to the speech-specific subset of the MSP line of chips (MSP50C6XX chip family) was sold by TI to Sensory, Inc. Sensory rebranded the chips as the Sensory SC-6x line. In October 2007, Sensory announced it would no longer accept new mask submissions for the SC-6x line. Orders for chips with existing masks will continue to be accepted for at least the next year. The companion devices to all versions of the speech chip were the custom 4-bit-interfaced 128Kbit (16KiB) TMS6100NL (AKA TMC0350) and 32Kbit (4KiB) TMS6125NL (a.k.a. TMC0355 a.k.a. TMS7125) read-only memories which were mask programmed with words required for a specific product. ALL versions of the LPC chips until the TSP50Cxx series support them. All versions
