Zilog’s Z8 Encore!
products, based on the 8-bit eZ8 CPU. Z8 Encore!
Zilog’s extensive line of 8-bit microcontrollers. The Flash in-circuit programming
capability allows the faster development time and program changes in the field. The new
eZ8 CPU is upward compatible with existing Z8
set of Z8 Encore! F083x series makes it suitable for a variety of applications including
motor control, security systems, home appliances, personal electronic devices, and
sensors.
The on-chip Flash controller can be bypassed, allowing direct control of the Flash signals
through the general purpose input/output (GPIO) pins. The Flash memory can be
programmed faster by controlling the Flash memory signals directly. This method is
beneficial when programming a large number of devices and is helpful to those who are
developing the multi-site gang programmers.
Z8 Encore! F083x reuses most of the existing test modes from Z8 Encore! XP F0822
Series Flash Microcontrollers. It supports the following modes for programming the
Flash:
•
•
Only one of the above test modes can be selected at a time. Multiple combinations result
in pin conflicts. Each test mode is enabled by setting the corresponding enable bit in the
on-chip debugger’s (OCD’s) test mode register. Flash test mode can also be enabled by
pulling the TESTMODE pad Low if certain conditions on the option bit states are
satisfied.
Flash test mode allows testing of the Flash memory. It is used at wafer level testing by
UMC with the VPP pin to improve programming/erase times. It is also used on packaged
part without the use of the VPP pin.
The setup conditions required for the Flash test mode are:
1. Apply Vdd = 3.3 V type (UMC specification), AVDD = 3.3 V.
2. Drive the TESTMODE pad Low.
3. Wait for the Power-On Reset (POR) to exit. POR is clocked by an internal RC
