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 compression 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.
