9.1 56F8014 Information

Please contact your Freescale sales representative or authorized distributor for device/package-specific

BSDL information.

The TRST pin is not available in this package. The pin is tied to VDD in the package.

The JTAG state machine is reset during POR and can also be reset via a soft reset by holding TMS high

for five rising edges of TCK, as described in the 56F8000 Peripheral User Manual.

Part 10 Specifications

10.1 General Characteristics

The 56F8014 is fabricated in high-density CMOS with 5V-tolerant TTL-compatible digital inputs. The

term “5V-tolerant” refers to the capability of an I/O pin, built on a 3.3V-compatible process technology,

to withstand a voltage up to 5.5V without damaging the device. Many systems have a mixture of devices

designed for 3.3V and 5V power supplies. In such systems, a bus may carry both 3.3V- and 5V-compatible

I/O voltage levels (a standard 3.3V I/O is designed to receive a maximum voltage of 3.3V

± 10% during

normal operation without causing damage). This 5V-tolerant capability therefore offers the power savings

of 3.3V I/O levels, combined with the ability to receive 5V levels without damage.

Absolute maximum ratings in Table 10-1 are stress ratings only, and functional operation at the maximum

is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent damage to

the device.

Unless otherwise stated, all specifications within this chapter apply over the temperature range of -40ºC to

105ºC ambient temperature over the following supply ranges:

VSS = VSSA = 0V, VDD = VDDA = 3.0–3.6V, CL < 50pF, fOP = 32MHz

CAUTION

This device contains protective circuitry to guard

against damage due to high static voltage or electrical

fields. However, normal precautions are advised to

avoid

application

any

voltages

higher

than

maximum-rated voltages to this high-impedance circuit.

Reliability of operation is enhanced if unused inputs are

tied to an appropriate voltage level.
