All Rights Reserved < Revision 5.02 > 3 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.) Picture of the “8051 ISP 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. ©2010 Nuvoton Technology Corporation. All Rights Reserved < Revision 5.02 > 4

User can use NuTiny-ML51EB to develop and verify the application program easily. The ML51 runs up to 24 MHz at a wide voltage range from 1.8V to 5.5V, and contains up to 64/32/16/8 Kbytes Flash called APROM for programming code. The ML51 Flash supports In- Application-Programming (IAP) function, which enables on-chip firmware updates. Partial Flash can be optionally configured as Data Flash programmed by IAP and read by IAP or MOVC instruction. The ML51 includes an additional configurable up to 4/3/2/1 Kbytes Flash area called LDROM, in which the Boot Code normally resides for carrying out the In-System-Programming (ISP). To facilitate mass production programming and verification, the Flash is allowed to be programmed and read electronically by parallel Writer/Programmer or In-Circuit-Programming (ICP) with Nu-Link. Once programmed and verified, the programmed code can be protected by the Flash lock mechanism for not being read out by any external programming tool. The ML51 provides rich peripherals including 256 bytes of SRAM, 4/2/1 Kbytes of auxiliary RAM (XRAM), up to 43 general purpose I/O, two 16-bit Timers/Counters 0/1, one 16-bit Timer2 with three-channel input capture module, one Watchdog Timer (WDT), one Self Wake-up Timer (WKT), one 16-bit auto-reload Timer3 for general purpose or baud rate generator, two UARTs with frame error detection and automatic address recognition, two ISO7816 Smartcard interface, two SPI, two I2C, 12 enhanced PWM output channels with dead zone control, two analog comparators, eight-channel shared pin interrupt for all I/O ports, and one 12-bit ADC at 500 ksps. There are a total of 30 sources with 4-level-priority interrupts capability. The ML51 is equipped with four clock sources and supports on-the-fly clock switching via software control. The four clock sources include two sets of external crystal inputs (HXT, LXT), 38.4 kHz internal oscillator, and one 24 MHz internal high-precision ±2% oscillator. The ML51 provides additional power monitoring detection such as power-on reset and 7-level brown-out detection, which stabilizes the power-on/off sequence for a high reliability system design. Through the high performance of 1T 8051 core, low power performance of ML51 and rich well- designed peripherals, the ML51 benefits for low-power, battery powered devices, general purpose, home appliances, or motor control system.
