T48L is a 64-bit dual-core x86 embedded microprocessor introduced by AMD in March 2011. This processor is a member of the AMD Embedded G-Series formerly codenamed "eBrazos" with CPU cores based on the Bobcat microarchitecture and is fabricated on a TSMC 40 nm process. The T48L operates at a base frequency of 1.4 GHz with a TDP of 18 W. It supports single-channel DDR3-1066 memory.

Cache

[Edit/Modify Cache Info]

Cache Organization Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes.

Expansions

"eBrazos" processors integrate one 5-port, 8-lane PCIe Gen 1/2 (5 GT/s) controller. Four GPP lanes are configurable as up to four x4/x2/x1 wide (e.g. 1x2 + 2x1) links, the remaining four lanes are reserved for a UMI link to the chipset. The recommended AMD A50M "Hudson-M1" and A55E "Hudson-E1" controller hubs provide four PCIe Gen 1/2 lanes configurable as up to four x4/x2/x1 links, a 32-bit, 33 MHz PCI interface (A55E only), 6 × SATA Gen 1/2/3 (6 Gb/s), 14 × USB 1.1/2.0, 2 × USB 1.1, a Gb Ethernet MAC (A55E), HDA, LPC, SPI, SMBus, GPIO.
