Description
IS42S32200L-7TL is a high‑speed synchronous DRAM (SDRAM) from ISSI in the IS42S family. It is designed as system memory with multi‑bank organization and burst‑access capability, operated on a synchronous clock with the standard SDRAM command set (ACT, READ/WRITE, PRECH, REFRESH). The -7 denotes a 7 ns speed grade; -L indicates a RoHS lead‑free (packaging/variant) option, and the device typically runs at about 3.3 V (check the exact variant). Data width and burst length (often x8/x16 with BL4/BL8) vary by part option, and timing parameters such as tRCD, tRP, tRC and CAS latency (CL) govern performance. Common applications are as main memory in embedded systems, consumer electronics, and other devices requiring fast RAM. For exact density/organization, voltage, package, and timing specifics, consult the official ISSI IS42S32200L-7TL datasheet, since variant options exist.
Equivalent
Equivalents depend on package, voltage and speed. For a reliable cross-reference, please provide:
- package type (e.g., SOJ28, TSOP)
- operating voltage (e.g., 3.3V, 1.8V)
- timing/speed (-7TL ≈ 7 ns)
- temperature range
With that, I’ll give pin‑compatible equivalents from ISSI and other vendors (e.g., Alliance Memory, Cypress).

Pinout
Pin count: 54 pins (TSOP II package).
Function: IS42S32200L-7TL is a 64-Mbit (2M × 32) synchronous DRAM (SDRAM) with a 32-bit data I/O bus, multiplexed address lines and two banks. It uses standard SDRAM control signals: CS, CK/CK#, CKE, RAS, CAS, WE, and DQ[31:0]. The “-7” denotes 7 ns speed; “-TL” indicates a lead-free variant and particular packaging.
