How robust is LPC2103 Flash memory read protection??

Does anybody know how robust is the LPC2103 flash read protection?? I'm switching from LPC2124 to LPC2103. This new chip is great!! I did not use LPC2104 due to there is no read protection. There were lots of discussions and attacking on the LPC2114-2294 and LPC213x/4x flash memory read protection. But had never seen the chip's protection proven could be bypassed so far. Could we just forget about read protection on old chips and move discussions over to LPC2103?? I'm very interested in the new LPC2103: - 8-bit's pricing (Atmega168 US$2.38, LPC2102 - US$2.46 Digikey 100pcs pricing). Well, US$0.30 1.8V LDO needed. - All timers can produce PWM (Only 2 PWM channel in LPC2124 when both UARTs used up). Can be event counters also (not in LPC2124) - 70Mhz Single Clock, 32-bit 5V tolereant I/O, small footprint. - 2x Fifo-ed Uart, 2x I2C, 2x SPI, 8channel ADC, Wow!! - Battery Backed RTC - And mostly will have larger 64-256KB flash memory in future!! It's the most perfect chip I've ever seen. But, how is the flash memory read protection?? anybody...?? Please help to provide some answer...Many thanks in advance!! Regards
