[TUHS] Moore's Law: PDP-11 1970 vs TI's low-power small chip for under 20 cents.

[sjenkin at canb.auug.org.au]

The specs aren’t that quite equivalent:

	1Kb SRAM vs 48K core memory, 32-bit vs 16-bit CPU and 24Mhz vs 1MHz, but what does that clock mean in MIPS?

Anyone want to take a stab at the Moore’s Law constant over 55 years, given the specs non-equivalence?

	~2.5M times price change, = 2^22 times.

	 In 1970, they proposed buying a PDP-11 for about $65,000.  [ $535,000 in 2025 according to US Inflation Calculator ]

Texas Instruments Introduces MSPM0C1104 as the Smallest Available Microcontroller

	<https://linuxgizmos.com/texas-instruments-introduces-mspm0c1104-as-the-smallest-available-microcontroller/>

	Measuring only 1.38mm², this wafer chip-scale package MCU is 38% smaller than existing alternatives.

	The MSPM0C1104 includes a 
		24MHz Arm Cortex-M0+ core (32-bit), 
		16KB of flash memory, 
		1KB of SRAM, 
		a 12-bit ADC with three channels, and 
		six GPIO pins. 

	It also supports standard communication interfaces, 
		including UART, SPI, and I2C.

	Additional features include 5V-tolerant I/Os, 
		a 1-channel DMA controller, 
		a CRC-16 accelerator, and 
		various timers, including a 16-bit advanced timer 
		and two 16-bit general-purpose timers.

	These MCUs operate in an extended temperature range from -40°C to 125°C 
	and support supply voltages from 1.62V to 3.6V.

	The MSPM0 series starts at $0.16 in 1,000-unit quantities, with multiple configurations available.
