T40E is a 64-bit dual-core x86 embedded microprocessor introduced by AMD in May 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 T40E operates at a base frequency of 1.0 GHz with a TDP of 6.4 W. It supports single-channel DDR3-1066 memory and integrates a Radeon HD 6250 GPU operating at up to 280 MHz.

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.

Graphics

This processor integrates an AMD Radeon GPU of the Evergreen series with two compute units based on the TeraScale 2 microarchitecture. It features 80 stream processing units, 8 texture units, 16 Z/Stencil ROP units, and four color ROP units. Decoding of H.264, VC-1, MPEG-2, and DivX/Xvid video streams is accelerated by a UVD 3 engine. Two independent display controllers natively support the DisplayPort 1.1a protocol on two 4-lane DDIs, a Flat Panel Display (LVDS) link on the first port, and a VGA interface with 30 bpp color depth and up to 400 MHz pixel clock. The eDP, DVI, and HDMI protocols are supported with additional components. The maximum display resolution is 1920 × 1200 at 60 Hz.
