Metro RP2350 take 5 🔄🌟🤞

Sometimes mistakes are made in prototyping; that's why they're prototypes. The error in rev D was funny: while making the QFN80 footprint, the pins got placed clockwise rather than widdershins. Not surprisingly, that board didn't come up at all, so here's a full rip-up and reroute, with the correct pinout this time! Fingers crossed. Hopefully, this is the final revision, and we can move on to other RP2350 boards we have cooking.

Microcontrollers: Deciphering Types and Memory Configurations

Microcontrollers serve as the backbone of embedded systems across a multitude of applications, with varying types and memory configurations to meet diverse needs. This article provides an in-depth analysis of microcontrollers, categorizing them based on their bit architecture (8-bits, 16-bits, 32-bits, and 64-bits) and memory configurations (embedded and external). By examining the characteristics, capabilities, and applications of each type, this article offers insights into selecting the most suitable microcontroller for specific embedded system requirements.

Microcontrollers play a crucial role in powering embedded systems, ranging from consumer electronics and automotive applications to industrial automation and IoT devices. Understanding the different types of microcontrollers and their memory configurations is essential for engineers and developers to design efficient and reliable embedded solutions.

Types of Microcontrollers

2.1. 8-bit Microcontrollers:

8-bit microcontrollers are known for their simplicity, low cost, and suitability for handling basic control tasks. They find applications in entry-level consumer electronics, home appliances, and simple automation systems.

16-bit Microcontrollers:

16-bit microcontrollers offer improved processing power and memory capabilities compared to their 8-bit counterparts. They are commonly used in more advanced consumer electronics, automotive systems, and medical devices.

32-bit Microcontrollers:

32-bit microcontrollers provide enhanced performance, higher computational capabilities, and support for complex algorithms. They are widely deployed in industrial automation, networking equipment, and high-end consumer electronics.

64-bit Microcontrollers:

64-bit microcontrollers represent the pinnacle of processing power, enabling advanced computation, multitasking, and handling of large data sets. They find applications in high-performance computing, embedded servers, and data-intensive applications.

Memory Configurations

Embedded Memory:

Microcontrollers with embedded memory integrate non-volatile memory (e.g., flash memory) directly onto the chip, offering a compact and cost-effective solution. Embedded memory is suitable for applications requiring fast access to program code and data storage.

External Memory:

Some microcontrollers utilize external memory interfaces to connect to additional storage devices such as RAM, EEPROM, or SD cards. External memory configurations provide flexibility for expanding storage capacity and accommodating larger datasets in embedded systems.

Applications and Use Cases

Microcontrollers, with their diverse types and memory configurations, cater to a wide range of applications including:

Consumer Electronics: Smartphones, wearables, home automation devices.

Fruit Jam RP2350B credit-card mini computer with all the fixin's 🍓🍇💾

We were catching up on a recent Hackaday hackchat with Eben Upton (https://hackaday.io/event/202122-raspberry-pi-hack-chat-with-eben-upton) and learned some fun facts: such as the DVI hack for the RP2040 was inspired by a device called the IchigoJam (https://www.hackster.io/news/ichigojam-combines-strawberry-and-raspberry-to-deliver-a-raspberry-pi-pico-powered-educational-micro-66aa5d2f6eec). We remember reading about this back when it was an LPC1114, now it uses an RP2040. Well, we're wrapping up the Metro RP2350 (https://www.adafruit.com/product/6003), and lately, we've been joking around that with DVI output and USB Host support via bit-banged PIO, you could sorta build a little stand-alone computer. Well, one pear-green-tea-fueled-afternoon later we tried our hand at designing a 'credit card sized' computer - that's 3.375" x 2.125", about the same size as a business card (https://hackaday.com/2024/05/07/the-2024-business-card-challenge-starts-now/) and turns out there's even a standard named for it: ISO/IEC 7810 ID-1 (https://www.iso.org/standard/70483.html).

Anyhow, with the extra pins of the QFN-80 RP2350B, we're able to jam a ridonkulous amount of hardware into this shape: RP2350B dual 150MHz Cortex M33 w/ PicoProbe debug port, 16 MB Flash + 8 MB PSRAM, USB type C for bootloading/USB client, Micro SD card with SPI or SDIO, DVI output on the HSTX port, I2S stereo headphone + mono speaker via the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/tlv320dac3100irhbt/2353656), 2-port USB type A hub for both keyboard and mouse or game controllers, chunky on-off switch, Stemma QT I2C + Stemma classic JST 3-pin, EYESPI for TFT displays, 5x NeoPixels, 3x tactile switches, and a 16-pin socket header with 10 A/D GPIO + 5V/3V/GND power pins. The PSRAM will help when we want to do things like run emulations that we need to store in fast RAM access, and it will also let us use the main SRAM as the DVI video buffer.

When we get the PCBs back and assembled, what should we try running on this hardware? We're pretty sure it can run DOOM. Should that be first? :) We also need a name. Right now, we're just calling it Fruit Jam since it's inspired by the IchigoJam project.
