TMS320LC548 的说明

The TMS320LC548 fixed-point, digital signal processor (DSP) (hereafter referred to as the '548) is based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. The processor also provides an arithmetic logic unit (ALU) that has a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. The '548 also utilizes a highly specialized instruction set, which is the basis of its operational flexibility and speed.

Separate program and data spaces allow simultaneous access to program instructions and data, providing the high degree of parallelism. Two reads and one write operation can be performed in a single cycle. Instructions with parallel store and application-specific instructions can fully utilize this architecture. In addition, data can be transferred between data and program spaces. Such parallelism supports a powerful set of arithmetic, logic, and bit-manipulation operations that can all be performed in a single machine cycle. In addition, the '548 includes the control mechanisms to manage interrupts, repeated operations, and function calls.

This data sheet contains the pin layouts, signal descriptions, and electrical specifications for the TMS320VC548 DSP. For additional information, see the TMS320C54x, TMS320LC54x, TMS320VC54x Fixed-Point Digital Signal Processors data sheet (literature number SPRS039). The SPRS039 is considered a family functional overview and should be used in conjunction with this data sheet.

The '548 signal descriptions table lists each terminal name, function, and operating mode(s) for the 144-pin thin quad flatpack (TQFP).

The letter B in front of CLKRn, FSRn, DRn, CLKXn, FSXn, and DXn pin names denotes buffered serial port (BSP), where n = 0 or 1 port. The letter T in front of CLKR, FSR, DR, CLKX, FSX, and DX pin names denotes time-division multiplexed (TDM) serial port.

The pin assignments table to follow lists each signal quadrant and BGA ball pin number for the 144-pin BGA package.

The '548 signal descriptions table lists each terminal name, function, and operating mode(s) for the TMS320LC548GGU.

包装方式

您可以根据器件数量选择不同的包装方式,包括完整卷带、定制卷带、剪切带、管装或托盘。

定制卷带是从整盘卷带上剪下来的具有连续长度的剪切带,是一种可以对特定数量提供产品批次及生产日期跟踪的包装方式。根据行业标准,使用黄铜垫片在剪切带两端各连接一个 18 英寸的引带和尾带,以直接送入自动组装机。涉及定制卷带的 TI 订单将包含卷带费用。

剪切带是从整盘卷带上剪下来的特定长度的编带。根据所申请器件数量的不同,TI 可能会使用多条剪切带或多个盒子进行包装。

TI 通常会根据库存情况选择将管装托盘器件以盒装或者管装或托盘形式发货。所有器件均会按照 TI 内部规定的静电放电和湿敏等级保护要求进行包装。
