The device operates at a maximum clock frequency of 143MHz with 5.4ns access time, suitable for mid-range embedded and industrial memory applications. The quad-bank architecture enables concurrent operation by allowing one bank to be precharged while another is being accessed, hiding precharge latency for sustained throughput. Each of the four 67,108,864-bit banks is organized as 8,192 rows by 512 columns by 16 bits. The device supports programmable CAS latency of 2 or 3 clocks and programmable burst lengths including 1, 2, 4, 8, and full page modes. The -7TLI designation indicates the 143MHz speed grade (7ns tCK), industrial temperature range (-40C to +85C), TSOP-II package with matte tin (Sn) leads, and industrial grade qualification. This device is also available in a 54-ball TF-BGA (8x13mm) package for space-constrained applications.","working_principle":"The IS42S16160J-7TLI operates as a synchronous dynamic RAM where all input signals are registered on the positive edge of the system clock (CLK). The memory array consists of four independent banks, each containing 4M words of 16 bits. Access begins with an ACTIVE command that latches the bank select (BA0-BA1) and row address (A0-A12) to activate a specific row in the selected bank. A subsequent READ or WRITE command provides the column address (A0-A8) with A10 controlling auto precharge. Data is transferred in burst mode starting at the selected column, continuing for the programmed burst length (1, 2, 4, 8, or full page) in either sequential or interleave order. The auto precharge feature initiates row precharge at the end of the burst, reducing the need for explicit PRECHARGE commands. The DQML and DQMH signals provide byte-level data masking during write operations and output enable\/disable control during reads. Periodic refresh is required with 8192 cycles every 64ms, performed automatically via auto refresh (CBR) or maintained during low-power states via self refresh mode.","pin_description":"
