We urgently need to know the minimum power consumption of LPC1102 when configured with CPU working mode.In other words, I want to know the minimum CPU configurable frequency.Here are some materials I found for your reference.(the first document is the source code of LPC1102, the second document says the power consumption is 130ua/MHZ, so I want to know the lowest frequency it can reach, the third document page 11, 7.14 clock and power control.)Thanks for your help.

Hi, JinChi,

Regarding the core clock frequency, it can reach up to 50MHz, but we do not specify the minimum clock frequency, in other words, I think the clock frequency can be any value as you want. We gave the spec of 130uA/MHz, generally, the power consumption is proportional to the clock frequency in a limited range of clock frequency, but for extreme clock frequency for example 1KHz, there is a minimum value, but we do not specify in data sheet.

Hope it can help you
