3 Functional Description

Figure 3-1 – FT51A Block Diagram

The FT51A acts as a USB hub supporting two downstream ports; the internal 8051 core and other

peripherals (SPI, UART, etc.) and an external downstream port (typical devices can be a mouse,

keyboard, mass storage device, etc.). The hub can optionally be disabled (under register control)

resulting in the 8051 core appearing at the upstream port.

3.1 Key Features

3.1.1

Functional Integration

Fully integrated MTP memory with built in shadow RAM for fast memory access , internally generated

clock, Power-On-Reset (POR) and LDO regulators.

3.1.2

8051 Core

The FT51A is based around the industry standard 8051 microcontroller capable of running at a maximum

frequency of 48MHz. The core is an ultra-high performance, speed optimized single-chip 8-bit embedded

controller dedicated for operation with fast on-chip memories.
