and some more references at that (almost) same 55c
price point, this one moves a column, but does have
more Flash, more ram, more timers, and
is quite a new step for Lumbering Infineon into a
low-price pool. There are many Asian vendors with
small 8051's, but it is good to see a serious industrial/automotive
vendor hit the low price points.

prices range from Euro 0.39 (US $0.55) to Euro 0.72 (US $1.01) in

there was free give away of XC822 based development boards on embedded

Did you score some ?

Scanning the data: nice devices, extremely well resourced for a
TSSOP16 pin device; unlike TI.
they are 5.5V and can drive power fets directly.
They also have ECC flash!.

A couple of minor design decisions have me ???
* They have RTC, and good RTC HW, but 'forgot' to
include a Crystal support - just one RTCIN pin ?
(also no HF crystal support - perhaps unreliable?)
* BOD protects the core, but seems not settable above
~2.9V
- A ~4.5V setpoint would be good for mosfet drive protection ?

The ADC is fast, so perhaps that is for SOA usage ?

Some good ROM features, but unclear if the non MDU models have still-
working MathLibs?

hm, I wasnt hunting much :)

i scored:
- XC822 touch demo (includes FT232 based programmer)
- renesas "rtos evaluatuor" ? H8S, + sram, made as USB dongle, assumed
with some loader
- st8 discovery kit OF COURSE (includes STM32 based programmer)
- silabs ir slider kit (c8051f326 based programmer + silabs mcu + ir
detectorstuff)
- some NEC kit with LCD (maybe also with onboard programmer, need
check out)

some pencil's and one non digital memory device :)
(paper based notebook!)

I must have missed something, What is a XC822 ?

thanks
