Previous Lattice releases.
Changed device status for LC4064ZC and LC4128ZC to production release and updated/added
AC and DC parameters as well as ordering part numbers for LC4064ZC and LC4128ZC devices.
Improved leakage current specifications for ispMACH 4000Z. For ispMACH 4000V/B/C IIL, IIH
condition now includes 0V and 3.6V end points (0  VIN  3.6V).
Added 132-ball chip scale BGA power supply and NC connections.
Added 132-ball chip scale BGA logic signal connections for LC4064ZC, LC4128ZC and
LC4256ZC devices.
Added lead-free package designators.
Hot socketing characteristics footnote 1. has been enhanced; Insensitive to sequence of VCC or
VCCO. However, assumes monotonic rise/fall rates for Vcc and Vcco, provided (VIN - VCCO) 
3.6V.
Improved LC4064ZC t
and f
Improved associated internal timing numbers and timing adders (version v.2.1).
Added ispMACH 4000V/B/C/Z ORP Reference Tables.
Enhanced ORP information in device pinout tables consistent with the ORP Combinations for I/O
Blocks tables (table 6, 7, 8 and 9 in page 9-11).
Corrected GLB/MC/Pad information in the 256-fpBGA pinouts for the LC4256V/B/C 160-I/O ver-
sion.
Added the ispMACH 4000 Family Speed Grade Offering table.
Added the ispMACH 4128ZC Industrial and Automotive Device OPNs
Added the ispMACH 4032ZC and 4064ZC Industrial and Automotive Device OPNs
