AD6426 Preliminary Revision 2.3
(Changes from Revision 1.0)
Number
Date
Description of Change
1
5/19/98
Motorola Serial Display mode added.
2
5/19/98
TXENABLE NMI function freeing up the IRQ6 pin added.
3
5/19/98
Dimensional tolerances for BGA package outline drawing added.
4
5/19/98
Memory I/F timing specs separated into characteristics and requirements.
5
5/19/98
Dual band control signals renamed- BANDSELECT0 is multiplexed with GPIO[2], BANDSELECT1
is multiplexed with GPIO[1]. For DB radios requiring a single Bandselect bit, BANDSELECT0 is
enabled. For DB radios requiring 2 Bandselect bits then both BANSELECT0,1 can be enabled.
These signals were previously referred to as BANDSELECT and DCSSEL.
6
5/19/98
VBC and radio I/F diagram in Figure 6 updated to show a generic DB radio I/F.
7
5/19/98
DAI I/F Pins updated to be consistent with DAI Box users manual.
8
5/19/98
GPIO[7:0] Pin functions in Mode D (Table 24) were incorrectly listed as being all Tristate outputs.
The correct function is GPIO7 = TRI and GPIO[6:0] = O.
9
5/20/98
Requirements for 32kHz crystal for slow clocking added.
10
5/20/98
Pin functions in Emulation mode GPO 0,6,7 in Table 24 are renamed to reserve.
11
5/20/98
Memory Interface Timing Specification: read timing specs changed to max with the exception of
Control Processor data hold and Parameters broken out separately into requirements and
characteristics.
12
6/9/98
In Fig 24 the following pins were incorrectly labeled and thus changed;
a) Pin 45 from HWR to UBS
b) Pin 46 from LWR to LBS
c) Pin 98 from GND to VDD
d) Pin 99 from VDD to GND
