| 15:41.48 | ceene | DocScrutinizer05: what about lattice FPGAs? |
| 15:42.04 | ceene | they're tiny and some of them even have free as in freedom tools |
| 15:42.45 | bencoh | what about power/battery? |
| 15:42.56 | DocScrutinizer05 | huh? |
| 15:44.09 | DocScrutinizer05 | ceene: the silego are mixed signal configurable integrated circuits. The logic functions are not as massive as in a FPGA |
| 15:44.42 | ceene | i know, but i worry that they decide to discontinue products so soon... |

| 15:45.27 | DocScrutinizer05 | they relabeled one product, since they - I guess - used a die shrink to fix a tiny SiErr |

| 15:46.05 | ceene | first example for this fpga family is an IR Rx/Tx :) |
| 15:46.48 | ceene | it's also that... when I don't hate VHDL and FPGAs I love 'em |
| 15:46.54 | ceene | it's a hard balance to maintain |
| 15:47.01 | DocScrutinizer05 | look: latice smallest: 640 LUT. Silego: 25 LUT/macrocells + 4 comparators |
| 15:47.28 | ceene | and what about price and power consumption? |
| 15:48.08 | DocScrutinizer05 | static power: latice 35µA, silego 0.3µA |
| 15:48.53 | DocScrutinizer05 | an FFGA isn't the righr component for our usecase |
| 15:48.59 | DocScrutinizer05 | FPGA |
| 15:49.42 | DocScrutinizer05 | the silego are more like ASICs |
| 15:53.42 | ceene | https://hackaday.io/project/6592-dipsy |
| 15:53.51 | ceene | funny things people do with lattice's fpgas |
| 15:54.58 | DocScrutinizer05 | sure, they are nice chips, but not exactly what we need here |
| 15:57.21 | DocScrutinizer05 | we use them here to replace a maybe 4 or 4 'traditional' analog (comparators, opamps) and logic (2-LUT, 3-LUT, like 7400 4 gate NAND. Also D-FF and counters, low power oscillator, delay etc) chips |
| 15:57.36 | DocScrutinizer05 | 4 or 5 |
| 15:58.05 | wpwrak | the killer feature are the integrated analog comparators. we use them heavily. lattica don't have that. |
| 15:58.32 | wpwrak | ah, we're synchronized ;-) |
| 15:58.38 | ceene | oh, that's right |
| 15:58.43 | ceene | these are pure digital circuits |
| 15:58.44 | DocScrutinizer05 | and I don't know if latice can even do that, anyway the Silego have a OTP ROM to freeze the config, so they are not per se 'Field Programmable' |
| 15:59.06 | ceene | http://imgur.com/a/4vBfT |
| 15:59.16 | ceene | we opened up an android phone yesterday, btw |
| 15:59.27 | ceene | that's all there is to see |
| 16:05.22 | bencoh | what did you expect? :) |
| 16:05.41 | ceene | don't know... something :) |
| 16:05.47 | bencoh | huhu |
| 16:06.47 | DocScrutinizer05 | ceene: see for example U801 in https://neo900.org/stuff/kicad/proto_v2/2016-11-08/neo900__proto_v2__by_eeshow.pdf#8 |
| 16:08.09 | DocScrutinizer05 | it does analog comparator and AD, and it provides a duty-cycle power saving for the two LVM221 RF-sensors |
| 16:08.56 | ceene | u801 is gps rf lna |
| 16:09.06 | DocScrutinizer05 | so this little chip saves us a maybe 5 others, or alternatively we had to offload all those tasks to the main CPU |
| 16:09.18 | ceene | u806 i guess |
| 16:09.32 | DocScrutinizer05 | sorry U806 |
| 16:09.40 | ceene | i see |
| 16:09.48 | ceene | yep, no fpga will do that |
| 16:09.55 | ceene | they're just not designed for it |
| 16:10.08 | DocScrutinizer05 | exactly |
| 16:12.32 | ceene | well, time to go home |
| 16:12.32 | ceene | cya! |
| 16:13.04 | DocScrutinizer05 | and the recent addition of I2C is just a very nice option that came with the new GP5 chips (which I ranted about yesterday). Before we planned to use a GP4 (without I2C) for exactly the same task, except the ADC obviously |
| 16:13.50 | DocScrutinizer05 | before that we planned for an analog comparator (or opamp) and doing the duty-caycle and ADC in OMAP |
| 16:15.13 | DocScrutinizer05 | in OMAP we had to use a PWM IP for that, so the CPU can go asleep while the PWM still handles reducing the power-on time for the greedy LMV221 |
| 16:16.17 | DocScrutinizer05 | problem: with such approach we need to make sure the comparator doesn't fire a IRQ during settle time and shutdown with evey cycle of duty |
| 16:17.25 | DocScrutinizer05 | so the comparator needed some enable function too. And then we still had no bias compensation for possible drift between the two LMV221 |

| 16:32.30 | Joerg-Neo900 | anyway we are using the SLG36533 which is not being phased out. The 'twin' SLG46531 however is, but obviously just to relabel it to SLG46537 and do a tiny SiErr fix along with the die shrink (and/or bonding pad rearrangement) both chips probably have seen for the new even more tiny MSTQFN-22 package |
