8051 ISP Programmer
1 Introduction
ISP is the acronym of In-System Programming, which makes it possible that the user can update the MCU’s
program memory under the software control without removing the mounted MCU chip from the actual end product.
The USB-stick-like tool “8051 ISP Programmer”, as shown in the following picture, is used to perform the ISP
function when the MCU’s LDROM is pre-programmed with the Nuvoton Standard ISP Code and CONFIG bits are
properly configured. In addition, since this tool can save the programming data downloaded from the host, it is able
to perform the off-line operation. This feature is especially useful in the field without a host PC.
Note:
The ISP function can work only when the ISP code has resided in MCU’s LDROM. To let users easily use the ISP
function, some of the 8051 MCU products have the “Nuvoton Standard ISP Code” pre-programmed in LDROM and
CONFIG bits properly configured before shipping. Please contact Nuvoton for detailed product information. (The
“Nuvoton Standard ISP Code” is also included in the folder [(3) Nuvoton Standard ISP Code]. The user may program
it by himself using a universal programmer.)

The ISP Interface
PL: Pull-low control.
Some 8051 MCU parts need its special I/O pins to be tied to ground to boot from LDROM for ISP operation. Using
pull-low control can release these I/O pins for their normal function. In other words, these pins needn’t be tied to
ground in the target system but pulled low by the ISP Programmer for ISP operation.
RST: Reset control to the 8051 MCU.
The ISP Programmer will send reset signal to control the 8051 MCU for ISP operation.
VCC: Power supply from the target system. In off-line operation, the Programmer is powered by the target system.
DTA: Serial data to/from the 8051 MCU. (Single-wire Communication Interface)
GND: Ground.

2 Hardware
According to the I/O pins used for booting from LDROM after reset, there are several connection types between the
8051 MCU and the ISP Programmer, as shown in the following table. Some parts don’t need any I/O pins, but need
CONFIG to be properly configured, such as W78E(I)051D, W78E(I)052D and W78E(I)054D. Some parts need only
I/O pins, such as W78E(I)058D, W78E(I)516D, etc. Some parts need not only I/O pins but also CONFIG properly
configured, such W78E(I)RD2A, W77E(L)516A, etc. The following sub-sections will show the connection diagrams
for these connection types.
