Its dual-port architecture allows two independent bus masters — such as a DSP and a microcontroller — to read from or write to the same memory location simultaneously without external arbitration logic. ## 68-PLCC footprint and rework considerations Housed in a 68-lead PLCC with J-leads (package code 68-LCC J-Lead, supplier device package 68-PLCC 24.23x24.23 mm), this surface-mount package is a legacy form factor common in mid-1990s through 2000s designs. The J-lead profile allows socketed or soldered mounting; for rework, a hot-air station with a PLCC nozzle and preheat from the board underside is typical. The package is supplied in Tray format. ## Supply voltage and temperature grade Operating from a single 4.5V to 5.5V rail, the CY7C138-15JXC is a 5V-logic part — it cannot be mixed with 3.3V or lower-voltage buses without level translation. The commercial temperature grade (0°C to 70°C) restricts deployment to controlled indoor environments; no industrial or automotive temperature range is offered on this variant.","metaTitle":"CY7C138-15JXC Infineon 32Kbit Dual-Port SRAM, 15ns","metaDescription":"CY7C138-15JXC 32Kbit dual-port asynchronous SRAM, 4Kx8, 15ns access, 5V, 68-PLCC.
