No stock-holding claim is made here. ## What 150 ns access time means for bus timing The 150 ns access time is the maximum delay from address valid to data valid on the parallel bus. For a microcontroller running at 8 MHz with a 125 ns bus cycle, this part meets the setup timing with margin — the CPU inserts one wait state per read cycle. At 10 MHz (100 ns cycle), two wait states are needed, which halves the effective read throughput to ~5 MB/s. The parallel interface means all 8 data lines and the address bus are driven directly — no serial protocol overhead. This suits systems where the memory bus is already routed for SRAM or NOR flash and the designer needs non-volatile storage without a SPI/I²C translation layer. ## Memory organization and write cycle timing Organized as 128K x 8 bits, the full 1 Mbit array is byte-addressable. The 10 ms write cycle time per word or page means a full-chip rewrite of 128 KB takes roughly 21 minutes if written byte-by-byte — page-mode writes reduce this significantly. The part does not operate at 3.3 V; a level translator or separate 5 V regulator is required if the rest of the board runs on a lower core voltage. This covers most factory-floor, outdoor telecom, and automotive cabin applications. ## Compliance and documentation RoHS3 compliant — no restricted substances above the threshold limits. The manufacturer provides a full material declaration and REACH compliance data upon request through the standard documentation portal.","metaTitle":"Microchip AT28C010-15TU-T 1Mbit Parallel EEPROM, 150 ns","metaDescription":"Active 1Mbit parallel EEPROM, 150 ns access, 128K x 8, 4.5-5.5V, -40 to +85°C, 32-TSOP.
