This data sheet provides complete design documentation for the second-generation devices of the TMS320 family. This facilitates the selection of the devices best suited for user applications by providing all specifications and special features for each TMS320 member. This data sheet is divided into four major sections: architecture, electrical specifications (NMOS and CMOS), timing diagrams, and mechanical data. In each of these sections, generic information is presented first, followed by specific device information. An index is provided for quick reference to specific information about a device.
ADVANCE INFORMATION concerns new products in the sampling or preproduction phase of development. Characteristic data and other specifications are subject to change without notice.

The TMS320 family of 16/32-bit single-chip digital signal processors combines the flexibility of a high-speed controller with the numerical capability of an array processor, thereby offering an inexpensive alternative to multichip bit-slice processors. The highly paralleled architecture and efficient instruction set provide speed and flexibility to produce a MOS microprocessor family that is capable of executing more than 12.5 MIPS (million instructions per section). The TMS320 family optimizes speed by implementing functions in hardware that other processors implement through microcode or software. This hardware-intensive approach provides the design engineer with processing power previously unavailable on a single chip. The TMS320 family consists of three generations of digital signal processors. The first generation contains the TMS32010 and its spinoffs. The second generation includes the TMS32020, TMS320C25, and TMS320E25, which are described in this data sheet. The is a floating-point DSP device designed for even higher performance. Many features are common among the TMS320 processors. Specific features are added in each processor to provide different cost/performance tradeoffs. Software compatibility is maintained throughout the family to protect the user's investment in architecture. Each processor has software and hardware tools to facilitate rapid design.
The TMS32010, the first NMOS digital signal processor in the TMS320 family, was introduced in 1983. Its powerful instruction set, inherent flexibility, high-speed number-crunching capabilities, and innovative architecture have made this high-performance, cost-effective processor the ideal solution to many telecommunications, computer, commercial, industrial, and military applications. Since that time, the TMS320C10, a low-power CMOS version of the industry-standard TMS32010, and other spinoff devices have been added to the first generation of the TMS320 family. The second generation of the TMS320 family (referred as TMS320C2x) includes four members, the TMS320C25, TMS320C25-50, and TMS320E25. The architecture of these devices is based upon that of the TMS32010. The TMS32020, processed in NMOS technology, is source-code compatible with he TMS32010 and in many applications is capable of two times the throughput of the first-generation devices. Its enhanced instruction set (109 instructions), large on-chip data memory (544 words), large memory spaces, on-chip serial port, and hardware timer make the TMS32020 a powerful addition to the TMS320 family. The TMS320C25 is the second member of the TMS320 second generation. It is processed in CMOS technology, is capable of an instruction cycle time of 100 ns, and is pin-for-pin and object-code compatible with the TMS32020. The TMS320C25's enhanced feature set greatly increases the functionality of the device over the TMS32020. Enhancements included 24 additional instructions (133 total), eight auxiliary registers, an eight-level hardware stack, 4K words of on-chip program ROM, a bit-reversed indexed-addressing mode, and the low-power dissipation inherent to the CMOS process. An extended-temperature range version (TMS320C25GBA) is also available. The is a high-speed version of the It is capable of an instruction cycle time of less than 80 ns. It is architecturally identical to the original 40-MHz version of the TMS320C25 and, thus, is pin-for-pin and object-code compatible with the TMS320C25. The TMS320E25 is identical to the TMS320C25, with the exception that the on-chip 4K-word program ROM is replaced with a 4K-word on-chip program EPROM. On-chip EPROM allows realtime code development and modification for immediate evaluation of system performance.
