'''Am2045''' (later renamed '''Am2045A'''), codename '''[[codename::Kestrel]]''', was [[Ambric]]'s original flagship [[MPPA]] introduced in late 2006. This model was made of {{ambric|am2000#Architecture|43 Brics}} arranged as a grid of about 5x9, making up a total of 344 {{arch|32}} [[RICS]]-like cores operating asynchronously at 1-333 MHz. This model was later replace with {{\\|Am2045B}}.

Originally this chip was supposed to have 45 Brics, hence the '2045' which was supposed to have 360 cores. However the final model only had 43 bric for 344 cores instead. Earlier models might have had only 42 brics at one point for 336 cores.

== Architecture ==
{{main|ambric/am2000#Architecture|l1=Am2000 § Architecture}}
The Am2045 is made of 43 homogeneous 'Brics' laid out in a 5 by 9 grid to form 344 cores and 344 RAM units.

General layout:
* 43x Brics
** 2x Computer Unit (CU)
*** 2x SRD {{arch|32}} CPU
*** 2x RD {{arch|32}} CPU
** 2x [[RAM]] Unit (RU)
*** 4x 2 KB [[SRAM]] bank

== Cache ==
The Am2045 contains 43 Brics, each with its own [[RAM]] Unit (RU) of 13 kB of SRAM for a total of 559 kB of SRAM.

== Memory controller ==
{{integrated memory controller
| type               = DDR2-400

* [[has feature::JTAG]]
* 128x [[has feature::GPIO]] @ 100 MHz
* [[has feature::serial flash]]
