Tel: 617/329-4700 Fax: 617/326-8703 FEATURES 38 ns Instruction Cycle Time (26 MIPS) from 13.00 MHz Crystal ADSP-2100 Family Code and Function Compatible with New Instruction Set Enhanced for Bit Manipulation Instructions, Multiplication Instructions, Biased Rounding, and Global Interrupt Masking 2K 24 Words of On-Chip Program Memory RAM 2K 16 Words of On-Chip Data Memory RAM 4K 24 Words of On-Chip Program Memory ROM (ADSP-21msp59 Only) 8-Bit Parallel Host Interface Port Analog Interface Provides: 16-Bit Sigma-Delta ADC and DAC Programmable Gain Stages On-Chip Anti-Aliasing & Anti-Imaging Filters 8 kHz Sampling Frequency 65 dB ADC, SNR and THD 72 dB DAC, SNR and THD 425 mW Typical Power Dissipation @ 5.0 V @ 38 ns <1 mW Powerdown Mode with 100 Cycle Recovery Dual Purpose Program Memory for Both Instruction and Data Storage Independent ALU, Multiplier/Accumulator, and Barrel Shifter Computational Units Two Independent Data Address Generators Powerful Program Sequencer Provides: Zero Overhead Looping Conditional Instruction Execution Two Double-Buffered Serial Ports with Companding Hardware, One Serial Port (SPORT0) has Automatic Data Buffering Programmable 16-Bit Interval Timer with Prescaler Programmable Wait State Generation Automatic Booting of Internal Program Memory from Byte-Wide External Memory, e.g., EPROM, or Through Host Interface Port Stand-Alone ROM Execution (ADSP-21msp59 Only) Single-Cycle Instruction Execution Single-Cycle Context Switch Multifunction Instructions Three Edge- or Level-Sensitive External Interrupts Low Power Dissipation in Standby Mode 100-Lead TQFP GENERAL DESCRIPTION The ADSP-21msp58 and ADSP-21msp59 Mixed-Signal Pro- cessors (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 applica- tions 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 archi- tecture (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. The ADSP-21msp58/59 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 ADSP-21msp58/59 is available in a 100-pin TQFP package (thin quad flat package). In addition, the ADSP-21msp58/59 supports new instructions, which include bit manipulations–bit set, bit clear, bit toggle, bit test–new ALU constants, new multiplication instruction (x squared), biased rounding, and global interrupt masking.
