Winbond Releases first 10 MIPS Flash C51 !!
Winbond have supplied FLASH MTP 80C51 for some time, and have recently
added a NEW W77xx family of Turbo-51 cored controllers.
They offer WatchDOG operation, on Std FLASH controllers, extra IO ports,
and the newest family, the W77C, has a Dallas type FAST core, with
ROMLESS and FLASH variants.
This family places the C51 in the Speed/Resource lead, ahead of other 8 bit uC
XA.....: No FLASH, and non std tools
Dallas.: Closest Equiv, but Max's out at 8K OTP, 8 MIPS
AVR....: Max's out at 8K Bytes, 8 MIPS, in PLCC44 package. No BIT or Direct RAM support
Scenix.: At 2Kw, just 9.4% of the code space of W77E58
PIC....: Far less capable core, 5 MIPS, mostly OTP only
The romless W77C32 allows a socket replacement of Dallas 80C320/80C323, with MORE
RAM, and higher speed.
Previously, Turbo Core users were forced to choose OTP, to get 1K RAM.
Mandeno Granville offer support tools for ALL the Winbond Controllers.
We have Assemblers, Compilers, Emulators, Programmers, and Adaptors for
these advanced controllers.

- Full screen 'Borland' interface DbgX51, Multi Windowed, direct editing
- Source level Debug, and MIXED language SOURCE debug, allowing .ASM,C,MOD
- Serious, but Low Cost! - Bondout ICE just $NZ1995+
We offer tools for ALL suppliers C51's, so if you choose Analog Devices,
Atmel, Philips, Siemens or Winbond, your tools investment is protected.
W77p - Bondout Turbo Emulation, PLCC44 Probe
W77p uses a Bondout device, to emulate W77E58 devices.
- For Probe Emulation of PLCC44 W77E58
- Plugs into PLCC44 sockets
- 40MHz Bondout, for Full 10 MIPs Speed operation
Fe44 - Footprint Emulation, PLCC44 Probe
Fe44 uses a CPLD, and advanced BUS interfac, to provide CODE memory
Read/Write of P0,P2 regen signals, without using WRN, RDN lines - no
stolen Pin resource.
Simple libraries are included, to make the Debug virtually invisible,
and the Trice-52 allows 64K of emulation space, supporting future devices.
- For Probe Emulation of PLCC44 W78E
- Plugs into PLCC44 sockets
- Includes regen P0,P2 byte read/write, without using MOVX
Tiny Probe Emulation Solution
Mandeno Granville now offer a Tiny Probe, for their ICE tools.
As SMD packages become more common, and A/D precisions increase,
Emulation solutions are more difficult.
Conventional QFP ICE probes are extermely expensive, and delicate, plus
they disturb the GND design.
As our ICE tools have the advantage of NOT replacing the Controller,
we are able to offer a better solution.
The Tiny Probe is a Multiplexed, 20 Pin, 2mm Pitch Connector, that Emulates to
64K Bytes. It uses a 27C520 pinout, and has a very small routed PCB
footprint. It allows single sided PCB designs, and the Swap option on the
header allows designers to 'scramble' the DB and A8-15 lines, if required.
The Tiny Probe, also allows new freedom in design process, and enables
wider device choices.
Tiny Probe + Trice-52
Compact, 2mm Pin Header on target PCB
Minimum 20 Pin Emulation Interface
Allows PLCC and QFP packages to be used
Emulate all C51 variants, including Winbond 320/550
Full Speed, with Break Points
Single Step, Chip Edit Debug
Less invasive than uC ICE probe
Uses 'As Shipped' Silicon - no gotchas

Structured Text Language for C51's
The 'best fit' High Level language for the 51 core, is Mod51.
This structured Text langauge fits the C51 core better than C, and
produces very tight code - forget the vaporware / bloat products like java, and C++
Want to see some examples / Benchmarks
For more language details see Mod51 Summary
FLASH PSD813 Details
The WSI PSD813 series, offers an Ideal solution for larger systems.
With 128K BYTES of FLASH, and integrated RAM, this device
allows ISP Flash to be added to ALL Romless Winbond uC.
The W77C32 allows a socket replacement of Dallas 320/323, with MORE
RAM, and higher speed.
This offers In System Program, and tighter PCB layouts, allowing low RFI
designs. The integration of the LATCH removes a significant source of
RFI, and allows much shorter DBus trace lengths.
