*Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.DescriptionThe ADSP-21msp58/59 Mixed-Signal Processors (MSProcessor® DSPs) are fully integrated, single-chip DSPs complete with a high performance analog front end. The ADSP-21msp58/59 Family is optimized for voice band applications such as Speech Compression, Speech Processing, Speech Recognition, Text-to Speech, and Speech-to-Text conversion.
The ADSP-21msp58/59 combines the ADSP-2100 base architecture (three computation units, data address generators, and program sequencer) with two serial ports, a host interface port, an analog front end, a programmable timer, extensive interrupt capability, and on-chip program and data memory.
The ADSP-21msp58 provides 2K words (24-bit) of program RAM and 2K words (16-bit) of data memory. The ADSP- 21msp59 provides an additional 4K words (24-bit) of program ROM.It integrates a high performance analog codec based on a single chip, voice band codec, the AD28msp02. Powerdown circuitry is also provided to meet the low power needs of battery operated portable equipment. The product is available in a 100-pin TQFP package
(thin quad flat package).
In addition, the ADSP-21msp58/59 supports new instructions,
which include bit manipulationsbit set, bit clear, bit toggle,
bit testnew ALU constants, new multiplication instruction
(x squared), biased rounding, and global interrupt masking.
