Introduction:
Section 1. ”SAM3U Description”, Updated: 52 Kbytes of SRAM. 4x USARTs (SAM3U1C/2C/4C have 3), up to
2x TWIs (SAM3U1C/2C/4C have 1), up to 5x SPIs SAM3U1C/2C/4C have 4),
Table 1-1, “Configuration Summary”,EBI column updated, 8 bits for SAM3U1C/2C/4C
SAM3U4/3/2C rows FWUP replaces NO in FWUP,SHDN pins column

Figure 2-1 ”144-pin SAM3U4/2/1E Block Diagram” and Figure 2-2 ”100-pin SAM3U4/2/1C Block Diagram”
updated, SM cell removed; UART moved to peripheral area, added Flash Unique block, removed 12B from
ADC block, added SysTick counter and Fmax 96 MHz to M3 block. FWUP replaces WKUP in fig 2-1, FWUP
added to fig 2-2
Figure 2-2 ”100-pin SAM3U4/2/1C Block Diagram”, NWR1/NBS1, NXRP0, A0 removed from block diagram.
