Details of AMD Turion II Neo N40H and N54H microprocessors

In the second quarter 2010 AMD launched a slew of embedded microprocessors for AM3 and compact ASB2 platforms. The launch spanned four different families from Athlon II Neo to Phenom II XLT, and included two Turion II Neo models - N40L and N54L. As we recently learned, there are two other embedded Turion II Neo models, that were already launched earlier this year, or are about to be launched. These models were referenced in a public AMD embedded processor roadmap.

New models, AMD Turion II Neo N40H and N54H, add support for DDR3-1333 memory, but in many other aspects they are similar to N40L and N54L CPUs. The embedded Turions integrate a dual-channel DDR3-capable memory controller, and two CPU cores, each having 1 MB L2 cache memory. Turion II N40H is clocked at 1.5GHz, and consumes no more than 15 Watt. The N54H model operates at more respectable 2.2 GHz, but it has higher 25 Watt Thermal Design Power. The processors are packaged in ASB2 BGA package.

We couldn't find any embedded products with the AMD N40H microprocessor, although we found iBase ET850 CPU module that comes with the N54H. In addition to the N54H, the CPU module may also use Athlon II Neo N36L or Turion II Neo N54L processors. The board utilizes AMD 785E North Bridge and SB820M South Bridge chipsets, and supports up 4 GB of DDR3 memory. The ET850 has one SO-DIMM socket that can accept DDR3-800 memory for N36L and N54L CPUs, or DDR3-1333 for N54H microprocessor. AMD 785E NB integrates Radeon HD4200 graphics controller. Other integrated features of the iBase ET850 are 2 SATA III, 8 USB and 4 serial ports, HD Audio and a Gigabit LAN.
