The EZ-USB Technical Reference Manual introduces the EZ-USB integrated circuit, describing its block diagram, USB specification compliance, and the various transfer types (Bulk, Control, Interrupt, Isochronous). It also explains the 8051‑based microprocessor core, memory organization, and I/O port functions.
Further sections cover reset and power‑management features such as suspend, resume, and remote wake‑up, detailed register maps, AC/DC parameters, and the available package options (44‑Pin PQFP, 80‑Pin PQFP, 48‑Pin TQFP). The document serves as a comprehensive guide for developers designing with the EZ-USB controller.
| Package Type | 44‑Pin PQFP |
|---|---|
| Package Type | 80‑Pin PQFP |
| Package Type | 48‑Pin TQFP |
| Memory Sizes | 8‑KB ROM, 2‑KB RAM (version) |
The EZ-USB is an integrated circuit that combines a USB controller with an 8051‑based microprocessor core.
