When I first started to read about zOrigin on Crowdsupply, I was not really impressed. Meh… Yet another Bluetooth LE fitness tracker with a few sensors, and an Android app.
But as I read further, I found out the interesting part was inside the device: ZGLZ1BA, a custom chip manufactured using ZiP (zGlue Integration Platform) chip-stacking technology, which produces something similar to SiP (System-in-Package) but at a much lower cost and manufacturing lead time.
- “SoC” – ZGZL1BA ZiP with
- Dialog Semiconductor DA14585 16MHz 32-bit ARM Cortex M0 MCU with BLE
- Analog Devices AD8233 Heart Rate Analog Front End (AFE)
- Macronix MX25R4035F 2 Mbit Flash Memory
- MCube MC3672 Accelerometer
- Maxim MAX77734 Power Managment IC (PMIC)
- SiTime SIT1552 32 kHz Oscillator
- Vishay SI8466EDB MOSFET
- 30 passive components
- Package – 0.8-mm-pitch BGA package measuring 8.7 mm x 9.1 mm
- Sensors – Heart rate monitor, three-axis accelerometer, temperature sensor
- User Notifications – phone app via Bluetooth Low Energy (BLE), LED, vibration motor
- Power -25 mAh rechargeable battery good for 1-2 weeks on a single charge
- Dimensions – Board: 27 x 11mm; 3D-printed enclosure: 33 x 16 x 11 mm
The company has developed a demo Android mobile apps that interface with zOrigin over a Bluetooth Low Energy (BLE) connection, and will release the source code for the mobile apps as a reference.
There’s also Origin Dev Board in the works, which breaks out all the pins and functionality of the ZGLZ1 chip, and includes a PMOD connector, as well as two electrode pads and cables for heart rate monitoring.
The company makes some bold claims about ZiP technology. First, the technology is said to enable businesses of any size, and developers – including hobbyists and makers – to quickly design high-quality SoCs at low cost:
- Design Time – in Minutes
- Manufacturing Time – in Weeks
- Initial R&D – $100
The turn around and costs is lower than SiP, because the latter “is based on customized interposers to optimize performance and capacity, which require customization with prohibitive cost and development time”, while ZiP relies on zGlue SmartFabrics “smart and programmable silicon interposer that delivers high-level of integration with the fastest time to market”. So not many details are provided, but it’s supposed to be both cheaper and faster to manufacture. Such custom chips should mostly be interesting in space-constraints applications, as you’d be able to design much smaller PCB with an all-in-one chip.
The design is done in the company’s zCAD cloud based software to be released before the end of 2018, and a trial version will be available to backers. Designers will simply drag and drop chiplets – pre-fabricated ICs that are validated by zGlue to be part of the ZiP system – on top of the interposer, and then program the interconnects with digital interfaces such as I2C, SPI or JTAG.
Back to the crowdfunding campaign: zOrigin fitness tracker is available for $49, the development kit for $99, and you can also pledge $99 to get a pack of five ZGLZ1BA chips. Shipping is free to the US, but adds $5 to $10 to the rest of the world, and delivery is scheduled for then end of August 2018. A few more details about the technology may be found on zGlue website.
