Texas Instruments TMS320C6202GLS250

Overview

TMS320C6202GLS250 from Texas Instruments is a fixed-point digital signal processor (DSP) built on the VelociTI™ VLIW architecture, delivering 2000 MIPS at 250 MHz with eight 32-bit instructions/cycle, 3M-bit on-chip SRAM (2M-bit program/cache + 1M-bit dual-access data), and 32-bit external memory interface supporting SDRAM, SBSRAM, SRAM, and EPROM for real-time telecom baseband processing.

For engineers reviewing the TMS320C6202GLS250 datasheet, TMS320C6202GLS250 pinout, TMS320C6202GLS250 application, or TMS320C6202GLS250 equivalent, key selection criteria include its 384-pin GLS BGA package, 1.8-V core / 3.3-V I/O voltage scheme, 3-channel McBSP support for T1/E1 framing, and 4-channel DMA with auxiliary channel - all critical for multichannel voice/data gateway designs.

Technical Context

The TMS320C6202GLS250 implements a dual-path VelociTI™ VLIW CPU with two register files (A/B, 32 × 32-bit), eight functional units (six ALUs, two 16-bit multipliers), and load-store architecture enabling two multiply-accumulates per cycle (500 MMACS). Its instruction set supports conditional execution, saturation, bit-field manipulation, and byte/half-word/word addressing.

It integrates a flexible PLL clock generator (x1, x4, x6, x7, x8, x9, x10, x11 multipliers), 32-bit expansion bus (XBus) with master/slave capability for PCI bridge interfacing, and three McBSPs compliant with AC97, SPI, ST-Bus, and T1/E1 framer standards - all operating within a 0.18-μm CMOS process.

Key Specifications

Pinout & Package

384-pin GLS Ball Grid Array (BGA) package, 18 mm × 18 mm footprint, 1.27-mm ball pitch, bottom-view layout with defined signal groups (EMIF, McBSP, XBus, PLL, power/ground). Pin mapping follows TI's standardized C62x GLS mechanical drawing SPRS104I.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fixed-point DSP applications.

Compared with TMS320C6202GLS250, the GNZ variant trades pin count and thermal headroom for compactness, while the C6202BGLS250 delivers identical speed in a more power-efficient node but demands redesigned power delivery - neither is pin-compatible without electrical and layout review.

FAQ

What is the maximum clock frequency supported by the TMS320C6202GLS250?

The TMS320C6202GLS250 operates at a maximum clock frequency of 250 MHz, corresponding to a 4-ns instruction cycle time. This rating is validated under recommended operating conditions (1.8-V core, 3.3-V I/O, case temperature ≤ 90°C) and enables 2000 MIPS throughput. Exceeding 250 MHz violates the device's production specifications and may cause timing violations or functional failure in the TMS320C6202GLS250.

Does the TMS320C6202GLS250 support SDRAM interfacing without external logic?

Yes, the TMS320C6202GLS250 features a glueless 32-bit external memory interface (EMIF) with dedicated SDRAM control signals (SDCTL, SDTIM) and burst-mode timing - enabling direct connection to standard SDRAM chips without address latches, bus transceivers, or custom timing logic. This capability is confirmed in the TMS320C6202GLS250 datasheet section "32-Bit External Memory Interface (EMIF)".

How many multichannel buffered serial ports (McBSPs) does the TMS320C6202GLS250 integrate?

The TMS320C6202GLS250 integrates three fully independent multichannel buffered serial ports (McBSP0, McBSP1, McBSP2), each supporting T1/E1 framing, AC97 audio, SPI, and ST-Bus protocols. Each McBSP provides up to 256 time slots and includes dedicated transmit/receive clocks, frame syncs, and data lines - all documented in the TMS320C6202GLS250 functional description and peripheral register tables.

What is the on-chip memory configuration of the TMS320C6202GLS250?

The TMS320C6202GLS250 contains 3M-bit of on-chip SRAM: 2M-bit allocated to program memory (64K × 32-bit instructions, configurable as cache or mapped program space) and 1M-bit allocated to dual-access data memory (128K bytes, organized as two 64K-byte blocks for concurrent read/write access). This structure is explicitly defined in the "3M-Bit On-Chip SRAM" section of the TMS320C6202GLS250 datasheet.

Is the TMS320C6202GLS250 pin-compatible with other C62x devices?

The TMS320C6202GLS250 is pin-compatible with the TMS320C6204 GLW package (340-pin BGA), differing only in the omission of the inner-row power/ground balls - a mechanical compatibility confirmed in the TMS320C6202GLS250 datasheet footnote. It is not pin-compatible with GNZ/GNY packages (352/384-pin) due to distinct ball maps and power distribution schemes.
