What the Nano L2100 is
The VIA Nano L2100 is the fastest Nano 2000 part, a 1.8 GHz single core from May 29, 2008. It runs one Isaiah core at 1.8 GHz with no turbo, so 1 core gives 1 thread. Cache is 64 KB data plus 64 KB instruction L1 with 1 MB of exclusive L2 on a 65 nm process. Power is rated at 25 W on NanoBGA2.
The L2100 tops the launch Nano line with a 9x multiplier on an 800 MHz V4 bus. Idle power drops to 500 mW. It exists because VIA wanted the quickest Isaiah single core for mainstream small desktops and notebooks at launch. The chip is soldered and cannot be replaced.
Socket and motherboard compatibility
The L2100 ships soldered on NanoBGA2 boards with a VIA companion chipset, pin-compatible with VIA C7 boards for OEM transitions. There is no socket upgrade and no board swap without replacing the whole device. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2 through the board chipset.
An 800 MHz VIA V4 bus ties the CPU to the companion chipset. Expansion hangs off the chipset.
Cooling is the device maker heat spreader for the 25 W envelope, with PowerSaver trimming draw to 500 mW at idle.
Upgrade paths
On NanoBGA2 the L2100 is the 2000-series ceiling and the chip is soldered, so a faster board means replacing the whole device. The VIA Nano L2200 at 1.6 GHz is the lower-power L-series option for device makers, and the VIA Nano U2400 covers fanless designs.
Frequently asked questions
What socket does the Nano L2100 use?
NanoBGA2, soldered, so it cannot be replaced or upgraded.
