MODE

Input-Static

Selects burst order. When tied to GND selects linear burst sequence. When tied to VDD or left

 

 

 

 

floating selects interleaved burst sequence. This is a strap pin and must remain static during

 

 

 

device operation. Mode pin has an internal pull up.

 

 

 

 

 

TDO

JTAG serial

Serial data-out to the JTAG circuit. Delivers data on the negative edge of TCK. If the JTAG

 

 

 

output

feature is not being utilized, this pin must be disconnected. This pin is not available on TQFP

 

 

Synchronous

packages.

 

 

 

 

 

TDI

JTAG serial

Serial data-in to the JTAG circuit. Sampled on the rising edge of TCK. If the JTAG feature is

 

 

 

input

not being utilized, this pin can be disconnected or connected to VDD. This pin is not available on

 

 

Synchronous

TQFP packages.

 

TMS

JTAG serial

Serial data-in to the JTAG circuit. Sampled on the rising edge of TCK. If the JTAG feature is

 

 

 

input

not being utilized, this pin can be disconnected or connected to VDD. This pin is not available on

 

 

Synchronous

TQFP packages.

 

 

 

 

 

TCK

JTAG-

Clock input to the JTAG circuitry. If the JTAG feature is not being utilized, this pin must be

 

 

 

Clock

connected to VSS. This pin is not available on TQFP packages.

 

NC

No Connects. 36M, 72M, 144M, 288M, 576M, and 1G are address expansion pins and are not

 

 

 

 

internally connected to the die.
