In addition to the P-TQFP-144-8 package, a P-BGA-160-1 package with a ball pitch of
1.0 mm and a size of 15 mm × 15 mm is supported (see

The Version 2.1 device requires two supply voltages, 3.3 V and 1.8 V. For compatibility
reasons, it is possible to operate the device off a single 3.3 V supply, with the 1.8 V
Delta Sheet
Version status in register VSTR changed from 02
The boundary scan part number changed to 142, the boundary scan ID changed to
1. A new BSDL file is required.
The pulse mask programming (registers XPM(2:0)) has to be adjusted.
The MCLK reference clock programming (registers GCM(8:1)) has to be changed.
Variable master clock frequency function always enabled (GCM2(4) = 1).
New feature “automatic short haul/long haul adjustment” available by setting
LIM0.EQON = 1.
Additional automatic resynchronization mode for T1 (new bit: FMR2.7 = AFRS).
Additional compare status field (mode 2) in SS7 mode (new bit: CCR5.6 = CSF2).
2048 kHz synchronization interface according o ITU-T G.703 Sec. 13 (E1). For more
information refer to online Application Notes http://www.infineon.com/falc.
No 5 V input levels are allowed due to technology restrictions (see
The currently unused ("N.C.") pins on V1.3 devices are used as "Core Voltage
Supply" (V
new technology the core voltage is 1.8 V (see
