Part 9 Joint Test Action Group (JTAG)
9.1 56F8033/56F8023 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 56F802X and 56F803X Peripheral Reference Manual.
Part 10 Specifications
10.1 General Characteristics
The 56F8033/56F8023 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 -40C to
125C 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
of
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.
