locations specified. Bits 16 and higher of the
preserve / authenticate location address will be
ignored.
Only the ‘last’ TEAclipper is limited-write. If the
firmware is paid-for, this is the TEAclipper which
holds financial value.
Recommended plate-through connector design
?
TEAclippers other than the ‘last’ are unlimited write
and the payload has no financial value.
Since the plate-through connector costs nothing, it’s
worth integrating it in every PIC PCB you design, just in
case you might want to use it to update the firmware at
a later date.
If any of the Vpp, PGC or PGD pins serve another
purpose in the circuit, these connections must be
isolated so that they do not interfere with, nor are
Low-Voltage Programming
Some PIC devices implement low voltage programming
using a PGM pin. The pin is pulled low during normal
use. When the TEAclipper is to be used to program the
device, a specific sequence of actions needs to be
followed:
affected by, the programming process. Capacitance on
these connections should be sufficiently low to allow
digital transitions of up to 1MHz in frequency.
If implementing Low-Voltage Programming, consider the
requirements for the PGM pin as detailed below in the
Low-Voltage Programming section. We typically
implement a 4k7 pull-down resistor and a pair of co-
located pads, one on either side of the board near the
edge, which allow the PGM pin to be temporarily
shorted high using a crocodile clip.

PIC firmware must be in INHX32 32-bit Intel Extended
Hex format. (This is the standard .hex file format
generated by MPLAB.) Any EEPROM or configuration
data must be embedded in the hex file.
Configuration, ID and EEPROM data must be
embedded in the hex data as recommended by
Microchip programming specifications. Refer to the
evaluation applications’ source code for examples.
Large Hex Images
Hex images greater than 64Kbyte. require one
TEAclipper per 64Kbyte or part thereof. Each
TEAclipper will program a separate 64K section of
memory.
The TEAclippers should be numbered TC1, TC2, etc.
During programming, they must be applied in the order
in which they are numbered.
TC1 will erase the microcontroller and program the
highest memory locations. The ‘last’ (i.e. highest
numbered) TEAclipper will program the lowest memory
locations, EEPROM, ID locations and configuration bits.
The following restrictions apply:
? The memory is not code protected prior to the use
of the last TEAclipper.
? Serialization values must reside in the lowest 64K
of memory.
? Authenticate may only be used on TC1.
? Preserve and authenticate should only be
specified on the TEAclipper which programs the
Note that for some LF parts, there is a minimum supply
voltage below which low voltage programming is not
permitted.
High-Voltage Programming
High voltage programming is only possible with
TEAclippers which include the high voltage
programming option. This option uses switched-mode
boost generator to provide required Vpp programming
voltage.
The boost generator performance is governed by two
parameters. The Precharge time governs the voltage at
the instant the high voltage is applied. The
PWMonTime governs the asymptotic voltage level.
The default Precharge and PWMonTime values assume
a 10K-22K pullup resistor to Vdd. This is the
recommended load and should be suitable for most
circuits. A very weak pullup may result in overvoltage;
too strong a voltage may result in undervoltage.
In cases of abnormal loads on Vpp, it is possible to
override Precharge and PWMonTime in HexWax
Explorer. A test mode is also provided, where a Vpp
square wave is output at 25Hz approx. The aim is to
enter programming mode with a voltage Vpp inside the
range specified in the device’s programming
specification.
Security
TEAclippers can be used to buy and sell firmware on a
per-copy basis. The degree of security offered by
