JEM-52

Features

• Supports debugging and programming for a variety of 8051 microcontrollers with on-chip debug interfaces: Atmel (AT89LP2xx/4xx), NXP/Philips (P89C95x), Micronas and others
• PC hosted via a USB port
• Automatically programs flash memory when loads a program for debugging
• Smart programming algorithm reduces flash memory writing time and prevents the MCU memory against premature wearing out
• Supports operations with external program and data memory devices
• Supports real-time and single steps program execution
• Enables four hardware breakpoints
• Enables Stack Overflow and Stack Underflow breakpoints (available not for all targets)
• Watch Dog Timer breakpoint
• Enables access to all target microcontroller resources when halted at a breakpoint
• JTAG clock frequency up to 4 MHz
• Software switchable Internal/External clock modes
• Built-in programmable frequency synthezator generates internal clocks in a range of 8 kHz to 100 MHz (available not for all targets)
• Software tracer records and displays preprogrammed set of parameters when emulation is halted on a breakpoint or after a step
• Requires no external power adapter - gets power from a standard USB PC port
• Featured with an embedded regulator powering the target with a programmable voltage - 1V to 5V/350 mA or supplies the target with a fixed voltage
• The JTAG logical I/O lines tolerate target input/output signals in the 1 to 5.5V range
• Conveniently controllable from the Phyton CodeMaster-52 integrated development environment (see software products below)
• The software set includes a C-like script language for hardware testing and device programming
• Dimensions - 4"x2-1/2"x1" (100x70x25 mm)
