The Advanced Micro Devices AM27X040 series MASK ROM, part number AM27X040-255JI, offers 4 Mbit (512K x 8) of non-volatile memory. This CMOS device features an asynchronous operating mode with a maximum access time of 250ns. It is housed in a 32-terminal PQCC (JEDEC R-PQCC-J32) package, designed for surface mounting with a terminal pitch of 1.27mm. The AM27X040-255JI operates within a supply voltage range of 4.75V to 5.25V, typically 5V, with a standby current of 100µA and a maximum operating current of 40mA. Its output characteristics are 3-state, making it suitable for applications requiring high-speed data storage and retrieval. This component finds application in industrial control systems, telecommunications infrastructure, and consumer electronics where reliable, mask-programmed firmware is essential. The operating temperature range is -40°C to +85°C.
