No direct pin-compatible replacement is listed on the official record. ## 15 ns access, 32K x 8 organization This is a 256Kbit asynchronous SRAM organized as 32K words by 8 bits, with a 15 ns access time and a matching 15 ns write cycle time (word, page). The parallel interface and 4.5-5.5 V supply make it a direct fit for legacy 5 V bus systems that need fast scratchpad or cache memory. The 0-70°C commercial temperature grade suits indoor, temperature-controlled environments — office equipment, test gear, or telecom line cards that stay within that range. ## 28-SOJ surface-mount package Housed in a 28-SOJ (Small Outline J-Lead) package, 0.300-inch body width, 7.62 mm. The J-lead footprint is reworkable with hot air — the leads are visible for inspection and the package body lifts without pulling pads if the preheat profile is right. Supplied in tube packaging. Surface-mount assembly with a 1.27 mm pitch typical for SOJ — standard pick-and-place handles it without special tooling.","metaTitle":"CY7C199-15VC Infineon SRAM, 256Kbit, 15 ns, 28-SOJ","metaDescription":"CY7C199-15VC Infineon asynchronous SRAM, 256Kbit (32K x 8), 15 ns access, 4.5-5.5 V, 0-70°C, 28-SOJ.
