RTS5111-01F-GR

The RTS5111-01F-GR is designed as a high-performance USB 2.0 card reader controller that integrates a USB 2.0 PHY, an SIE (serial interface engine), an 8051 MCU, a ROM, a RAM, and a memory card controller onto a single chip. It supports access to compact flash, microdrive, memory stick, memory stick PRO, secure digital, multimediacard, smart media, and xD-picture card. The built-in high-speed USB 2.0 device controller provides a 480Mbps transfer rate and offers backward compatibility with the 12Mbps USB 1.1 specification.

RTS5111-01F-GR has many features. (1)Compliant with universal serial bus specification revision 2.0. (2)Compliant with USB mass storage class bulk only transport specification rev.1.0. (3)Supports high-speed (480Mbps) and full-speed (12Mbps) data transfer. (4)Supports USB bus-powered operation. (5)Supports control, bulk, and interrupt USB data pipes. (6)Supports the following memory card interfaces: compactflash (CF), microDrive; SmartMedia (SM); secure digital (SD), multimediacard (MMC); memory stick (MS), memory stick PRO(MS-PRO) and xD-picture card (xD). (7)Supports hardware ECC (error correction code) function. (8)Supports hardware CRC (cyclic redundancy check) function. (9)Programmable clock rate for flash memory card interfaces. (10)Supports MS-PRO 4-bit parallel transfer mode. (11)Supports MS 4-bit parallel transfer mode. (12)Supports high-speed 50Mhz SD 4-bit card (version 1.1). (13)Support high-speed 52Mhz MMC 8-bit card (version 4.x). (14)Integrated fast 8051 microprocessor. (15)External NOR-type flash memory interface: ISP application for microprocessor program coding. And so on.

RTS5111-01F-GR has an internal ROM for MCU programs, and provides an external program flash memory interface for firmware update purposes. Firmware code can be downloaded through the USB interface to the it, and then be written into external flash memory automatically. With the external flash memory interface and the in-system-programming capability, product upgrades are easily realized. And so on.
