'18F010 and 18F020 ???'

Hi.
When looking through the variants of PIC's at Farnell,
I came across something called 18F010 and 18F020
in 8-pin packages.

What are these ? The Microchip web site didn't have
much on them. Are they "regular" 18F-series PIC's in
8 pin packages ?

Best Regards

If you ask, Farnell tell you they are 'obsolete' parts, which is wierd
because I don't think they are invented yet.

IIRC, they are both, as they were cancelled. We don't (yet) need an 18F
in an 8-pin package, and parts such as the 12F675 are the 'replacement'.
That's my fuzzy recollection anyhow, there is one dead link on uChip's site.

I downloaded the data sheet (41151a.pdf) for 18F0x0 PICs (Oct 2001) and was
eagerly awaiting its release since I needed an 8-pin flash MCU for a
particular project. But later I came to know that they have been replaced by
12F629 & 12F675. The initial part of the data sheet that briefly describes
the two PICs is reproduced below and it certainly sounds very impressive.

Hopefully, Microchip will reconsider introducing such chips in future!

       "The PIC18F010/020 Microcontroller Products pack all the
       advantages of the PIC18C architecture and the flexibility of
       FLASH program memory in an 8-pin package. The
       PIC18F010/020 products feature a 16-bit instruction set, small
       package footprints, low operation voltage of 2.0 volts, interrupt
       handling, internal programmable 8 MHz oscillator, onboard
       EEPROM Data Memory, Programmable Low Voltage Detector,
       Brown-out Reset, 8 x 8 Hardware Multiplier and 31 levels of
       hardware stack. Both devices are supported by outstanding
       development tools that include a low cost MPLAB®In-Circuit
       Debugger, programming support and Microchip's MPLAB®suite of
       development software."
