ISP1183 is a low-power Universal Serial Bus interface device with DMA. It complies with Universal Serial Bus Specification Rev. 2.0, supporting full-speed data transfer (12 Mbit/s). It provides full-speed USB communication capacity to microcontroller or microprocessor-based systems.
The Philips ISP1183 is a low‑power USB 2.0 full‑speed (12 Mbit/s) interface device designed for battery‑operated applications such as mobile phones, PDAs and MP3 players. It connects to a microcontroller or microprocessor via a fast parallel interface and includes an autonomous, multiconfigurable DMA engine.
The device offers up to 14 programmable USB endpoints, 2462 bytes of internal FIFO memory, an integrated 6 MHz crystal oscillator with PLL, and a 3.3 V regulator. It is supplied in an HVQFN32 lead‑free, halogen‑free package and operates over a wide voltage range (1.65 V–3.6 V I/O, 4.0 V–5.5 V core).
