Embedded flash controller
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 2
Controller wrapping a foundry embedded flash macro with read buffering and prefetch, program/erase sequencing, ECC and write protection.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| s_ahb | in | valid-qualified bus | 96 | |
| macro | inout | parallel | 128 |
Standards
No external standard applies.
Notes
The flash macro itself is foundry IP referenced through environment variables, never committed.
