The Pm29F004 is a 4 Megabit, 5 Volt-only Flash Memory with features including single power supply operation, high performance read, memory blocks architecture, automatic block erase and byte program, hardware data protection, low power consumption, and high product endurance.
The PMC Pm29F004 is a 4‑Megabit CMOS flash memory that operates from a single 5 V supply, offering low power consumption and fast access. It includes a 16 KB boot block (top or bottom), two 8 KB parameter blocks, one 96 KB main block and three 128 KB main blocks, with a software lockout feature for data security.
The device follows a standard JEDEC pin‑out and is offered in 32‑pin DIP and 32‑pin PLCC packages. It supports byte‑program, block‑erase, and chip‑erase operations, provides Data# polling and Toggle‑Bit status detection, and incorporates hardware data protection to prevent unintended writes.
| Memory size | 4 Megabit (512 K × 8) |
|---|---|
| Access time | 70 ns typical, 90 ns max |
| Standby current | 0.1 µA typical |
| Active read current | 15 mA typical |
| Program current | 40 mA typical |
| Temperature range | 0 °C to +70 °C (Commercial) |
| Boot block size | 16 KB |
| Parameter block size | 8 KB each (two blocks) |
The boot block guarantees 10,000 program/erase cycles.
Enabling the software lockout feature permanently protects the boot block from being reprogrammed.
Typical standby current is 0.1 µA.
