MPC823 AC Electrical Specifications
This document contains detailed information on power considerations, DC/AC electrical
characteristics, and AC timing specifications for the MPC823.
Note: Visit our website at www.motorola.com if you are using a frequency other than
25, 40, or 50MHz. Our website contains a spreadsheet that you can use to
calculate the timing for your specific system frequency.
This device contains circuitry protecting against damage from high-static voltage or electrical
fields. However, it is advised that precautions be taken to avoid application of any voltages
higher than the maximum-rated voltages to this high-impedance circuit. Reliability of operation
is enhanced if unused inputs are tied to an appropriate logic voltage level (either GND or VCC).

NOTES:
1.
Functional operating conditions are given in DC Electrical Characteristics (VCC = 3.0 - 3.6
V). Absolute maximum ratings are stress ratings only, and functional operation at the
maxima is not guaranteed. Stress beyond those listed may affect device reliability or cause
permanent damage to the device.
2.
CAUTION: The JTAG and GPIO input voltages cannot be more than 2.5 V greater than
supply voltage, this restriction applies also on Òpower-onÓ as well as on normal operation.
3.
5 Volt friendly inputs are inputs that tolerate 5 volts for JTAG and GPIO pins.
4.
If you are using Mask Revision Base #F98S (Revision 0), all pins except EXTAL and CLK4IN
are 5V tolerant inputs.

POWER CONSIDERATIONS
The average chip-junction temperature, TJ, in °C can be obtained from
TJ = TA + (PD ¥ qJA)
(1)
where
TA =
qJA =
PD =
PINT =
PI/O =
Ambient Temperature, ¥C
Package Thermal Resistance, Junction to Ambient, ¥C/W
PINT + PI/O
IDD x VDD, WattsÑChip Internal Power
Power Dissipation on Input and Output PinsÑUser Determined
For most applications PI/O < 0.3 ¥ PINT and can be neglected. If PI/O is neglected, an approximate
relationship between PD and TJ is:
PD =
K Õ (TJ + 273¥C)
(2)
Solving equations (1) and (2) for K gives
K=
PD ¥ (TA + 273¥C) + qJA ¥ PD
2
(3)
where K is a constant pertaining to the particular part. K can be determined from equation (3)
by measuring PD (at equilibrium) for a known TA. Using this value of K, the values of PD and TJ
can be obtained by solving equations (1) and (2) iteratively for any value of TA.
Layout Practices
Each VCC pin on the MPC823 should be provided with a low-impedance path to the boardÕs
supply. Each GND pin should be provided with a low-impedance path to ground. The power
supply pins drive distinct groups of logic on chip. The VCC power supply should be bypassed to
ground using at least four 0.1 mF bypass capacitors located as close as possible to the four
sides of the package. The capacitor leads and associated printed circuit traces connecting to
chip VCC and GND should be kept to less than half an inch per capacitor lead. A four-layer
board that employs two inner layers as VCC and GND planes should be used.
All output pins on the MPC823 have fast rise and fall times. Printed circuit (PC) trace
interconnection length should be minimized in order to minimize undershoot and reflections
caused by these fast output switching times. This recommendation particularly applies to the
address and data busses. Maximum PC trace lengths of six inches are recommended.
Capacitance calculations should consider all device loads as well as parasitic capacitances
due to the PC traces. Attention to proper PCB layout and bypassing becomes especially critical
in systems with higher capacitive loads because these loads create higher transient currents
in the VCC and GND circuits. Pull up all unused inputs or signals that will be inputs during reset.
Special care should be taken to minimize the noise levels on the PLL supply pins.

NOTES:
1.
The timing for BR output is relevant when the MPC823 is selected to work with the external bus arbiter.
The timing for BG output is relevant when the MPC823 is selected to work with the internal bus arbiter.
2.
The setup times required for TA, TEA and BI are relevant only when they are supplied by an external device
(and not when the memory controller or the PCMCIA interface drive them).
3.
The timing required for BR input is relevant when the MPC823 is selected to work with the internal bus arbiter.
The timing for BG input is relevant when the MPC823 is selected to work with the external bus arbiter.
4.
The D(0:31) and DP(0:3) input timings B18 and B19 refer to the rising edge of the CLKOUT in which the TA
input signal is asserted.
5.
The D(0:31) and DP(0:3) input timings B20 and B21 refer to the falling edge of the CLKOUT. This timing is
valid only under control of the UPM in the memory controller.
6.
The timing B30 refers to CS when ACS = Ô00Õ and to WE(0:3) when CSNT = Ô0Õ.
7.
The signal UPWAIT is considered asynchronous to the CLKOUT and synchronized internally. The timings
speciÞed in B37 and B38 are speciÞed to enable the freeze of the UPM output signals.
8.
The AS signal is considered asynchronous to the CLKOUT signal.

NOTES:
1.
The timings I39 and I40 describe the testing conditions under which the IRQ lines are tested when defined as
level sensitive. The IRQ lines are synchronized internally and do not have to be asserted or negated with
reference to the CLKOUT.
2.
The timings I41 and I42 are speciÞed to allow the correct function of the IRQ lines detection circuitry, and has
no direct relation with the total system interrupt latency that the MPC823 can support.

NOTES:

PSST = 1. Otherwise, add PSST times cycle time.
2.
PSHT = 0. Otherwise, add PSHT times cycle time.
3.
These synchronous timings deÞne when the WAIT_B signal is detected in order to freeze (or relieve) the
PCMCIA current cycle. The WAIT_B assertion will be effective only if it is detected two cycles before the PSL
timer expiration.

NOTES:
1.
T = shift clock cycle (220).
2.
This number is given for wbl(wait between lines) £ 2. For wbl=n {n>2} the timing will be (n+2)T.
3.
This number is given for wbl(wait between lines) £ 2. For wbl=n {n>2} the timing will be (n+2)T.
4.
Wait Between Frames (WBF) is a programmable parameter.
Tcyc is the cycle time of the LCD clock (shift clock). Tdelay is a circuit delay that is specified in
the AC electrical specifications. 1Ð16 lines is a time period that can vary between one scan line
and 16, depending on how the LCD controller is programmed in the VPW field of the LCVCR.
0Ð1,023 lines is a time period that can vary between 0 and 1,023 scan lines in the WBF field of
the LCVCR.
