So I want to implement the cortex-m3 with the 0.18 TSMC library, but I can't find its maximum frequency. Does anyone know the maximum frequency for the M3 in 0.18 technology?
I would recommend you check this with your FAE. This will depend on your configuration of CM3, the library you will use, and the experience of back-end, etc. I found some data which use:
Process = TSMC 28nm CLN28HPMRTL Configuration = 32 IRQs, Interrupt Priority Width 3, ETM, MPU & WIC present, 34 WIC lines, Bit-banding, Reset_all_registers 0, Full trace and debugArea = 0.04755 mm^2 (post optical shrink)Static power (mW) = 0.02926Frequency = 99MHz
Please note this achieved frequency may not be the maximum and it's only for your reference.
>Process = TSMC 28nm CLN28HPM
>Frequency = 99MHz
>Please note this achieved frequency may not be the maximum and it's only for your reference.
This is definitely NOT the maximum freq for 28nm, if it is we would be in trouble. :-)
But for 180nm low power process it might be right:
As Haiyan said, there are many factors. For example, even with 180nm process nodes, there are choice of 180g, 180ulp, 180ull and various choices within each types (https://www.embedded-computing.com/embedded-computing-design/squeezing-the-last-penny-of-efficiency-from-embedded-designs)
We cannot disclose much details here as this relates to technical details of libraries from foundaries. If you put your request via your local Arm sales office we can then share some more information.
