communications transformer (the FT-X3).

The transformer enables operation in the

presence of high frequency common-mode

noise on unshielded twisted-pair networks.

Properly designed devices can meet

the rigorous Level 3 requirements of EN

61000-4-6 without the need for a network

isolation choke. The transformer also offers

outstanding immunity from magnetic

noise, eliminating the need for protective

magnetic shields in most applications.

The FT 5000 Smart Transceiver and

the FT-X3 Communications Transformer

are designed to be used as a pair, and

therefore must be implemented together in

all designs. No transformer other than

the FT-X3 (or FT-X1 or FT-X2)

communications transformer may be used

with the FT 5000 Smart Transceiver or the

smart transceiver warranty will be void.

Migration Considerations

Most device designs that use the

previous-generation FT 3120/3150 Smart

Transceiver can transition to the FT 5000

Smart Transceiver. However, because

the two generations have different

supply voltage and memory architecture,

hardware redesign of the boards is

required to transition to the

FT 5000 Smart Transceiver.

See the

Series 5000 Chip Data Book

for more information about migrating

device designs for FT 3120/3150

Smart Transceivers to the FT 5000

Smart Transceiver.

End-to-End Solutions

A typical FT 5000 Smart Transceiver-

based device requires a power source,

crystal, external memory, and an I/O

interface to the device being controlled

(see Figure 7 for a typical FT 5000 Smart

Transceiver-based device).

IC Pin Descriptions

All digital inputs are low-voltage transistor-

transistor logic (LVTTL) compatible, low

leakage, 5V-tolerant. All digital outputs are

slew-rate limited to reduce Electromagnetic

Interference (EMI).

• On-chip RAM for stack segments

and RAMNEAR data.

• Mandatory external EEPROM that

holds configuration data and non-

volatile application variables.

• Reserved space for system use.

If a 64KB external serial EEPROM or flash

device is used, the maximum allowed size

of application code is 42KB as defined by

extended NVM area in the memory map.

An additional 16KB of the remaining space

can hold an external system firmware

image, in case a future firmware upgrade is

required.

Programming memory devices. Because

the FT 5000 Smart Transceiver does not

have any on-chip user-accessible NVM,

only the external serial EEPROM or flash

devices need to be programmed with the

application and configuration data. The

memory devices can be programmed in

any of the following ways:

• In-circuit programming on the

board.

• Over the network.

• Pre-programming before soldering

on the board.
