description
The MSP53C391 and MSP53C392 are catalog
MSP50C3x codes which implements the function-
ality of a slave speech synthesizer. They
communicate with a master microprocessor using
two control lines (R/W and STROBE) and either a
4-bit data bus (MSP53C391) or an 8-bit data bus
(MSP53C392).
Either the MSP53C391 or the MSP53C392 can
synthesize speech using several different com-
pression algorithms; LPC, MELP, or CELP. They
also can synthesize two-channel music using FM
synthesis.
See the MSP50C3x User’s Guide (literature
number: SLOU006B) for more information about
the MSP50C3x family.
