It is somehow weird to see MPC821 in this kind of device. The point of (Power)QUICC line is that the Communications Processor is some kind of RISC/VLIW core, that offloads various communications tasks and has firmware support for various serial telco protocols. I would not be too surprised if MPC821 and MPC860 are in fact the same hardware only with different firmware that somehow bitbangs the LCD interface by (ab)using the SCC channels (original m68k QUICC datasheet mentions that there is a way to make one of the channels behave like Centronics parallel port).

In any case PowerQUICC with LCD interface is a device that is quite obviously meant for something like dektop phone with large LCD, not for tablets.

Quite large usage of PowerQUICC were Cisco 17xx/26xx series routers (with 16xx using m68k QUICC) that were used by many telcos in early 2000's as "SHDSL modems". If you squint enough the m68k QUICC is an entire Cisco 2500 on a single chip (with the added benefit that the QUICC SCC can more or less do scatter gather DMA directly into IOS's particle buffer datastructure, which IIRC was not the case with the Z8530-derived USARTs in 2500).

We're still shipping hardware with PowerQUICC stuff in it, its used in a TDM/IP intelligent channel bank.

[kjs3]

Where are people still using TDM channel banks? As someone who spent far too much time with TDM networks (mostly replacing them) in the late 80s, genuinely curious.

[Aloha]

It's TDM internally, but converts to IP at the edge of the device.

It can still operate over TDM for legacy, but yeah, thats the answer.

NXP still sells those? Wow, e500 will never die huh
